Description of the invention: • Technical field of the invention The present invention relates to a substrate held on a stage, A substrate processing apparatus for performing predetermined processing on the held substrate and a substrate carrying method in the substrate processing apparatus. In particular, a substrate processing apparatus for carrying a substrate 2 201015147 on a substrate through an ejection pin (1 i f t p i η) disposed by a lifting operation of a platform, and a substrate carrying method in the substrate processing apparatus. Examples of the substrate include a glass substrate and a semiconductor wafer. [Prior Art] An example of a substrate processing apparatus that holds a substrate on a stage and performs predetermined processing on the substrate to be processed is a slit nozzle coater (si i t_nozzle) which is one of devices for manufacturing a liquid crystal panel. Coater). The slit nozzle coater applies a color filter or a TFT (Thin-Film Transistor) to a glass substrate to apply a photoresist (pho tores ist) liquid to the surface of the glass substrate. Configuration (refer to Patent Document 1). - The outline of the processing of the conventional slit nozzle coater 100 will be described with reference to Fig. 1 . In addition, among the components of the slit nozzle coater 1 shown in FIG. 10, the same components as the slit nozzle coater 1 of the embodiment of the present invention to be described later are added to the components. The same symbol of the element. As shown in FIG. 10(A), the conventional slit nozzle coater 1 is provided with a sputum adsorption platform 3, an ejector pin 41A, a slit nozzle 6 〇, and a control device 10A, etc. The delivery of the glass substrate K is performed by the substrate transport robot 9 having a robot (r〇b〇t hand) 93. It is assumed that the conventional slit nozzle coater 100 is in the initial private state of Fig. 1 (A). In other words, the ejector pin 41A is buried under the adsorption stage 3, and the robot 93 is located at the retracted position P1 while supporting the glass substrate K. The following is a description of each step. In the figure, the reversed white arrow indicates the direction of movement of the robot hand 93, and the black thick arrow indicates the direction of the movement of the ejector pin 41A. [Glass substrate receiving step] In the state of Fig. 10(A), first, the substrate transport robot 9 drives the robot hand 93 in the horizontal direction, and the glass substrate κ is supplied to the carry-in position P2a (refer to Fig. 10(B)). The loading position P2a is an upper position of the adsorption platform 3. Then, the control device 10A raises the ejector pin 41A to a predetermined position (see Fig. 10(C)). Then, the substrate transport robot 9 lowers the robot 93 supporting the glass substrate κ. The back surface of the glass substrate K is brought into contact with the tip end of the ejector pin 41A (see Fig. 10 (D)). After the glass substrate K abuts the ejector pin 41A, the robot 93 continues to descend, and when the glass substrate K and the robot 93 are separated by a predetermined interval D, the substrate transport robot 9 stops the lowering of the robot 93 (refer to the figure). 10(E)). Next, the substrate transport robot 9 drives the robot 93 in the horizontal direction to move to the retracted position P1 (see Fig. 10 (F)). Next, the control device 10A lowers the ejector pin 41A supporting the glass substrate K, and after the glass substrate K is placed on the adsorption stage 3, the glass substrate κ φ is positioned as needed, and then the glass substrate is vacuum-adsorbed. On the adsorption platform 3 (refer to Fig. 10 (G)). After the adsorption is completed, the coating is started by the movement of the slit nozzle 60 (refer to Fig. 10 (H)). [Glass substrate transfer step] 后 After the application is completed, the transfer of the glass substrate 基本上 is basically carried out in the reverse procedure of the above-described glass substrate receiving step. In other words, the vacuum adsorption of the glass substrate 吸附 adsorbed and held by the adsorption stage 3 is released, the support of the glass substrate 利用 by the ejector pin 41 上升 is raised, and the movement of the machine 4 201015147 is entered. The position P2a, the rise of the robot 93, the fall of _41A, and the retraction of the glass substrate κ by the robot 93. [Patent Document 1] Japanese Laid-Open Patent Publication No. 2008-55322 [Summary of the Invention] In the conventional slit nozzle coater 1A, the robot 93 is lowered when the load bearing glass substrate K is ejected onto the adsorption platform 3. The degree of the robot 93 when the φ substrate abuts against the tip end portion of the ejector pin 41A is set to a very slow value. The reason for this is to prevent the glass base from being defective or cracked by the collision when the back surface of the glass abuts against the tip end portion of the ejector pin 41A. Further, it is difficult to increase the speed of the lifting and lowering of the space in which the weight of the robot 93 is extremely heavy. However, as the use of liquid crystal panels has expanded and spread, the demand for liquid crystal production has increased. Therefore, the shortening of the tact time in the slit nozzle coater is an important issue. This subject is of course unique to the quilting nozzle coater. For example, it is suitable for use in an exposure apparatus, a cleaning apparatus, a drying apparatus, and an inspection apparatus for a liquid crystal panel, and a substrate processing apparatus that performs *delivery by a substrate transport robot other than a liquid crystal panel is generally applicable, and its solution is expected . In view of the above-mentioned problems, the object of the present invention is to provide a processing device for carrying a substrate to be processed on a platform by being lifted and lowered by a platform, thereby realizing work time and improving production efficiency. . The ejector pin support, the pin 41A, and the glass descent speed substrate K plate K are not used for manufacturing in the case of a panel. Further, the substrate ejector pin of the present invention is shortened 5 201015147 The above object is achieved by the present invention described below.

And the connecting rod 23 - body. The locking screw if 22 is screwed to the male screw 23a of the connector 23 in a state where the upper portion of the spring housing tube 24 is in contact with the spring housing tube 24. The spring receiving cylinder 24 is restricted from moving in the up and down direction by the lock nut 22. The spring U is attached to the small diameter portion 232 of the connecting rod 23 and the root side of the large diameter portion 231 in a state of being housed in the spring housing tube 24. The specific coil spring 25 is disposed in a state in which the upper end portion abuts against the large diameter portion 231 and the lower end portion abuts against the upper washer 28 and is contracted from the natural length. Therefore, because of the large diameter? The upper portion 231 is urged upward and the upper washer 28 is urged to form a gap L between the spring housing tube 24 and the upper washer 28. Accordingly, the tip end portion of the 1st pin 41 abuts against the glass substrate κ, and the coil spring 25 contracts when it is lowered, and a buffering action can be exerted. In other words, when the tip end portion of the ejector pin 41 abuts against the glass substrate κ, the tie rod 23 is lowered by the state of Fig. 9(A), and the coil spring 25 is contracted. At this time, the cylindrical collar 26, the lower washer 29, and the bolt 27 are lowered together with the connecting rod 23. That is, since the lower washer 29 is integrally attached to the small diameter portion 23 2 by the bolt 27, the cylindrical collar 26 and the lower washer 29 are lowered as the small diameter portion 23 2 is lowered. Therefore, the cylindrical collar 26 is separated from the upper collar 28' and the lower washer 29 is separated from the pin frame 42 (Fig. 9(B)). Further, a sensor 45 for detecting the support of the glass substrate Κ is disposed at a position below the ejector pin 41. As shown in FIG. 4, the sensor 45 is constituted by a microswitch having a switch portion 451 that outputs a turn-on signal SG1 by being pressed and turned on, and is transmitted through a bracket 452. The lower part. The mounting position is located below the bolt 27, and has a distance that is shorter than the distance of the bolt 27 from the gap L described above. That is, after the tip end portion of the ejector pin 41 abuts against the glass substrate κ, the rod 2 3 is further lowered and lowered along with the state of FIG. 9(B), and the cylindrical collar 26, the lower full ring 29, and the bolt 27 are attached. - Descent, as shown in Fig. 9(C)', the switch-on portion 4 51 is pressed by the bolt 27 to output the switch-on signal S G1. The ON signal S G1 is taken in a control device 1 后 which will be described later. Further, such a sensor 45 may be provided for each of the ejector pins 41. Alternatively, only a specific portion may be ejected. The pin 41 may be disposed to detect the support of the glass substrate κ. Further, at this time, the auger 25 is more contracted from the state of Fig. 9(B), and the gap L between the spring housing tube 24 and the upper washer 28 disappears. Accordingly, the spring housing tube 24 abuts against the upper gasket 28. As a result, the load of the glass substrate κ is supported by the pin frame 42. 201015147 In addition, the means for detecting the support of the glass substrate κ can be used, for example, by means of the sensor 45 of the type which is tightly connected as described above, for example, a transmissive photoelectric switch, a close-coupled photoelectric switch, a proximity sensor can also be used. (pr 〇X imity sensor) electromagnetic switch (magnet switch) and so on. In the case of using the above-described transmissive photoelectric switch, a transmissive photoelectric switch is disposed, and a stopper (light shield) for shielding transmitted light of the transmissive photoelectric switch is disposed at a position of the screw check 27, for example, by ejector pins. When the support glass substrate κ is lowered by 41, the stopper blocks the transmitted light of the transmissive photoelectric switch, so that the support of the glass base φ plate K can be detected. Further, the buffer mechanism 44 can adjust the strength of the buffering action, whereby the glass substrate K having a different weight can be appropriately buffered. Specifically, the strength of the pushing of the coil spring 25 is adjusted by loosening the second nut 2 2 ' to tighten and loosen the spring receiving cylinder 2 4 and the connecting rod 2 3 and changing the length of the gap L'. Further, the centering unit 5 disposed on the adsorption stage 3 has a sandwiching member 51 and a driving device 52 as shown in Fig. 2 . The loss-in member 51 is disposed in a pair on the left and right sides of the adsorption stage ❹ 3 in the Y direction. In each of the sandwiching members 51, it is useful to press the outline of both end faces of the glass substrate K in the γ direction. 5毫米。 The pad 53 is adjusted in advance, the gap between the 俾 and the carrier surface 31 of the suction platform 3 in the Z direction is 〇. 1mm~0. 3mm. The driving device 52 is configured, for example, in an air cylinder that is synchronized with each other and operates in the ±Y direction. The respective actuator parts are connected to the respective sandwiching members 51. The coating unit 6 is provided as shown in FIG. Two movable pillar portions 66 that are opposed to each other across a width wider than the width 13 201015147 of the adsorption platform 3; the slit nozzles 60 that are spanned between the two movable pillar portions 66 are crossed across the adsorption platform 3 is equipped with a door shape body. The two movable pillar portions 66 can be driven in the X direction by a linear motor (1 inear mo tor) 67X. The linear motor 67X is disposed in parallel with each other on the base 2 in the X direction. The slit nozzle 60 can be driven in the Z direction by a linear motor 67Z. The linear motor 67Z is disposed in each of the two movable pillar portions 66 along the Z direction. 〇

A slit-like stopper 6 3 for oozing the photoresist 20 is formed on the bottom surface of the glass substrate κ. Inside the slit nozzle 60, a manifold 64 that communicates with the internal flow path of the slit-shaped discharge port 63, and a communication path 65 in which the gap is normally set to several tens of μm are formed. The photoresist 2 extruded through the communication path 65 is applied to the glass substrate κ while the lip of the contact surface of the coating is wetted as the surfaces 60a and 60b'. The slit nozzle 60 is selectively disposed at the coating height H2 and the evacuation height H1 by the lifting operation by the linear motor 67z. The coating height is such that the gap between the surface of the glass substrate κ held on the bearing surface 31 and the slit nozzle/exit port 63 is about 1 〇〇//2 〇〇". The retracting height H1 is maintained on the bearing surface. The coating liquid supply unit 7 is provided with a coating liquid storage tank 71, a coating liquid transfer pump 72, and a non-return, as shown in Fig. 1 at a height at which the surface of the glass substrate κ of 31 is sufficiently separated from the discharge port 63. A check valve 73, 74. The coating liquid storage tank 71I is used for temporarily storing a groove of the photoresist liquid 20 which is a coating liquid of 201015147 (for example, an amount that can be applied to a plurality of glass substrates K). The liquid is connected to the coating liquid transfer pump 72 via the check valve 73. The coating liquid transfer pump 7 2 is connected to the slit nozzle 60 via a check valve 74. The coating is applied to a liquid crystal display (iiqUidcrystal).

Therefore, the coating liquid transfer pump 72 preferably has a small pulsation and has a short starting time at the start of supply and a good solvent resistance. And it does not produce coagulation or foaming of the liquid in the pump, and is rich in airtightness and durability, such as injection (Piston) pump or bellows pump, etc. In particular, since the syringe pump directly feeds the inner liquid by the piston, the responsiveness and the constant flow rate are excellent. On the other hand, since the telescopic pump indirectly sends the inner liquid, the air can be prevented. As shown in Fig. 6, the cleaning unit 8 includes a scraper 81, a blade drive device 82, a waste liquid receiving portion 83, etc. The scraper 81 is made of an elastomer such as synthetic rubber.

The cleaning liquid spray nozzle 81a and the drying air spray nozzle 81b are provided inside. Cleaning liquid spray nozzle 8 1 a is connected to the cleaning liquid storage tank filled with the cleaning liquid via a control valve pipe. The drying air injection nozzle 81b is a drying air storage tank that is connected to the compressed air for filling and drying via a control valve pipe. The blade driving device 82 can move the blade 81 in the ±γ direction, for example, a driving side pulley (pu 11 ey ), a driven side pulley, an endless belt attached to the two pulleys, and The rotary servo motor or the like that rotationally drives the drive side pulley is configured. The waste liquid receiving portion 83 is a metallic strip having a y-direction in the longitudinal direction and having a sub-two to ten-view area (area viewed in the Z direction) which is larger than the slit nozzle 60. Disk composition. In addition, it is also possible to provide an initializing device for returning to a constant state, such as a defrosting state in which the slitting discharge D ^ is called u D ό, in addition to the washing operation. The φ control device 10 is composed of an input/output device such as a touch panel, and an appropriate hardware mainly composed of a memory device and a microprocessor, etc., for making the hardware The interior of the Qiqiu 1乍• The hard disk device of the computer program; and the components of the drive unit such as the slotted boring machine and the square cloth changer 1. The substrate transport mechanism is abundant n ~ τ蛘Properly use the appropriate person ww interface circuit for data communication, etc., and output appropriate control signals to each component's squeezing nozzle coater 1 for a series of coating movements~ . The cymbal control device 10 specifically drives the control frame drive unit 4; 3 as follows. In other words, if the glass substrate 搬 is moved into the loading position Ρ 2 by the substrate transport robot 9 (see FIG. 8(B)), the control device 10 drives the control frame drive unit 43 to raise the glass substrate κ to the substrate. Standby position Ρ3, at which it stops. Specifically, the memory device in the control device 10 stores in advance the height of the substrate standby position Ρ3 (see FIG. 8(C)) at a position higher than the loading position Ρ2 (see FIG. 8 (Β)) of the glass substrate Κ. Data. When the glass substrate κ is held at the substrate standby position P3 (see Fig. 8(c)), the device 16 201015147 outputs the holding plate transport robot 9 . Moreover, the substrate of the 乂 signal is kept intact until the base arm 9 receives the robot 93. The control device 10 drives the control frame drive unit by the substrate transport mechanism; the Γ signal of the robot retreats the signal, and you carry the glass substrate K is placed on the suction flat plate ▲ under the ejector pin 41 of the substrate standby position P3. At this time, the drive control is performed until the glass base K is supported, and when the ON signal SG1 of the sensation glass substrate is not rimped, the control device 10 determines that the glass is made by the top pin 41. Base ^ (4) A W has some problems with the support of the ejector, and outputs an error signal. The port substrate transport robot 9 is provided with a motor 9 ι, an arm Μ, and a manipulator 93°. The manipulator 93 is formed to support the glass substrate K, and is driven by the motor 91. The arm 92 is configured to be movable in all directions of χγΖ0, and can be selectively disposed in the following retracted position Ρ1 and the carry-in position Ρ2 by horizontal movement. That is, the retreat position P1 is outside the adsorption platform 3, and when the Z direction is viewed, the adsorption platform 3 and the robot 93 have no common area. Further, the loading position P2 is directly above the suction platform 3, and the height of the robot 93 at this time coincides with the height of the retracted position P1. Further, the control of the robot 93 is performed by a control device provided by the substrate transport robot-arm 9 itself, which is different from the control device 1A.

First, the substrate transport robot/arm 9 drives the robot 93 that supports the glass substrate κ in the horizontal direction, and moves from the retracted position P1 to the carry-in position P2 (see Fig. 8(B)). When the glass substrate κ is moved from the retracted position P1 to the carry-in position P2, the robot 93 moves only horizontally. 〇 Next, the pin frame 42 is driven up by the drive control frame drive unit 43 by the control device 10, and the ejector pin 41 buried under the bearing surface 31 is raised. Thereby, the tip end portion of the ejector pin 41 protrudes from the bearing surface 31, and abuts against the back surface of the glass substrate κ located at the loading position P2. Then, by further raising the ejector pin 41, the coil spring 25 in the buffer mechanism 44 is contracted, and the ejector pin 41 is urged upward as shown in Fig. 9(B). In other words, the buffer mechanism 44 exerts a cushioning action when the tip end portion of the ejector pin 41 abuts against the glass substrate κ. When the ejector pin 41 supports the glass substrate κ, as shown in Fig. 9(C), the switch unit 201015147 4 51 is turned on. Then, the turn-on signal s G1 of each of the switch sections 45 1 is emitted. Then, the ejector pin 41 is supported by the tip end portion while supporting the glass substrate K, and the glass substrate K is held at the substrate standby position P3 (see Fig. 8(C)). Thus, the support of the glass substrate K is moved by the robot 93 to the ejector pin 41. Once the glass substrate K is held at the substrate standby position P3, the control device 10 holds the signal on the output substrate to the substrate transport robot 9. When the signal is held by the substrate, the substrate transport robot 9 drives the robot 93 from which the glass substrate κ has been detached in the horizontal direction to move to the retracted position ρ (refer to Fig. 8(D)). When the substrate transport robot 9 is retracted to the retracted position ρι, the substrate transport robot 9 outputs a robot retraction signal to the control device ι. Then, by the control device 1 〇, the signal drive control frame drive unit 43 is retracted by the above-described robot, and the drive pin frame 42 is lowered to lower the ejector pin 41. The ejector pin 41 supports the glass substrate κ while falling, and stops when το is completely buried below the bearing surface 31. Thereby, the glass substrate κ is carried on the bearing surface 31 (refer to Fig. 8 (E)). In this way, in accordance with the glass substrate receiving step S1, the glass substrate κ carried by the robot (10) into the loading position P2 is carried by the following points, which is different from the prior art. In other words, the ejector pin 41 is not lowered, but the ejector pin 41 is raised, and the glass substrate K is supported at the tip end portion thereof to be held at the moving position p2. The high standby position P3^HJ position of the substrate line can be moved horizontally by 1141. This 'manipulator 93 is only shortened, and can be reduced = less.' This part can reduce the working time. Productivity. In addition, the "manufactured substrate transport robot arm 9 201015147 is different from the batch control device of the slotted nozzle coater 1 , but the operation steps of the substrate transport robot 9 are small. The transmission/reception of the control data for the delivery of the 掳砝|ρ Λ α between the robot 93 and the ejector pin 41 can be shortened. Further, the buffer mechanism 44 acts as a buffer when the ejector lock 41 abuts against the glass substrate κ. The collision of the glass substrate 接受 received by the tip end portion of the ejector pin 41 is alleviated and absorbed. Therefore, it is possible to suppress defects or cracks in the glass substrate. [Centering step S2] 〇 The centering action is performed as follows. The centering unit 5 drives the sandwiching member 5 by the driving device 5 2 (refer to Fig. 2) to sandwich the glass substrate κ carried on the bearing surface 31 from both sides in the γ direction. As a result, the glass substrates κ are each positioned at equal intervals from the Υ direction of the adsorption stage 3, and the center line of the X-direction of the glass substrate and the center line of the y-direction direction of the bearing surface 31 (parallel through the center of the γ direction) The center line in the X direction) _ caused the so-called centering to be carried out. Then, the driving means 52 returns the sandwiching member 51 to the original position. [Coating Step S3] The β coating operation is performed as follows. After the centering is completed, first, vacuum pressure is generated in the vacuum suction hole 32 of the adsorption stage 3, and the glass substrate is vacuum-adsorbed to hold the glass substrate on the bearing surface 31. Then, by driving the linear motor 67A, the slit nozzle 60 is moved from the standby position Q1 to the coating start position Q2 (see Fig. 5>). Next, by driving the linear motor 67Z, the slit nozzle 6 is moved from the retraction height H1 to the coating height H2. Next, the coating liquid transfer pump 72 sends the photoresist liquid 20 to the slit nozzle 6A, and the photoresist 20 is oozing out from the slit-like discharge port 63. At this time, a film 20B (see FIG. 5) that is in contact with the glass substrate 1 is formed between the slit 63 201015147 outlet 63 and the surface of the glass substrate 1 (see FIG. 5). By driving the linear motor 67 in this state, The slit nozzle 60 is moved in the +χ direction (see Fig. 8(F)). The movement of the slit nozzle 60 is applied to the surface of the glass substrate K in the +χ direction of the photoresist 2〇. Upon reaching the coating end position Q3, the coating liquid transfer pump 72 stops the supply of the photoresist liquid 2, and the linear motor stops the driving of the movable stay portion 61 to stop the movement of the slit nozzle 60. Then, the drive line steep motor 67 turns 'The slit nozzles 6 〇 are raised to the retraction height. Then, the reverse ee rotation drive linear motor is at - . , and the λ direction ' opens the slotted discharge port 63 in the slit nozzle 60 to the cleaning unit 8 The upper part is stopped. [Scraping step S 4 ] The scraping operation is performed as follows: The first step is to drive the linear motor 6 7 Ζ to make the slit-like spout (see Fig. 6) in the slit nozzle 60 close to the arrangement. Next, the scraper 81 V-shaped groove liquid. The liquid cutting jet nozzle with the cleaning solution...sprayed and washed in +v a ^ , the knife drive device 82 drives the scraper 81 in the +Y direction. Accordingly, the slit-shaped $.1 ^ ^ discharge port 63 is washed. The scraper 81 — reaches the end in the +Υ direction, and the scraper is private. When the π*I is set to 82, the driving of the squeegee 81 is stopped. At the same time, the discharge of the cleaning liquid 82 is reversely driven until the knives 81 are stopped. Then, the squeegee driving nozzle 81b ejects the drying air. The drying is performed by air jet drying. The doctor blade 81 reaches the end portion of the slit-shaped discharge port 63 77 81 η which is broken by the γ γ, and the blade driving device 82 stops the driving of the blade 81 by 1 τ. The transfer step S5] the ejection of the drying air is also stopped. The glass substrate transfer operation is performed as follows. First, the vacuum pressure generated in the vacuum adsorption hole 32 of the adsorption flat 201015147 is destroyed. Then, the control device _ 10 transmits the drive control. The pivot driving unit 43 drives the pin frame 42 upward, and the ejector pin 41 protrudes from the suction platform 3 to abut against the glass substrate κ. Then, the glass substrate K is raised to the standby position of the substrate while the glass substrate K is being smashed. P3. At this time, also with the acceptance of the glass substrate - When the ejector pin 41 abuts against the glass substrate 缓冲, the buffering action is exerted. Accordingly, the glass substrate κ can be prevented from being defective or the cracked plate transporting robot 9 drives the robot 93 located at the retracted position Ρ1 in the horizontal direction. Moving to the carry-in position f ρ2, the control frame driving unit 43 is driven by the control device 1 to lower the ejector pin 41 supporting the glass substrate κ. By the lowering of the glass substrate κ, the robot 93 is coated. Then, the substrate transport robot-arm 9 is driven to receive the glass substrate 1 at the loading position Ρ2 (the robot 93 is horizontally transferred to the next process, for example, a vacuum drying process). Further, in the above-described embodiment, the initial state of the slit nozzle coater 显示 indicates that the ejector pin 41 is buried below the bearing surface 31. However, the ejector pin 41 is protruded to a predetermined height in advance. The predetermined height is also possible when the rising start position of the ejector lock 41 is made. In other words, the height of the glass substrate 被 that is carried into the loading position Ρ2 does not interfere with the ejector pin 41, for example, the top end of the output pin 41 is lower than the glass substrate κ that is moved into the loading position Ρ2. The position is regarded as a predetermined height, and the predetermined height is taken as the rising start position of the ejector pin 41. According to this, in the glass substrate receiving step S1, the rising distance of the ejector pin 41 required to raise the glass substrate 至 to the substrate standby position Ρ3 is shortened, so that it is possible to shorten the glass substrate Κ required to rise to the substrate standby position Ρ3. The time of the present invention is described above with reference to the embodiments of the present invention. However, the above-described embodiments of the present invention are merely illustrative of the scope of the present invention. The scope of the present invention is to be construed as being limited by the scope of the appended claims. That is, the structure, shape, size, material, number, and the like of the entire or a part of the slitting nozzle coater 1 can be variously changed in accordance with the gist of the present invention. Further, in the present embodiment, the substrate processing apparatus is a slit nozzle coater, and can be applied to other than the slit nozzle coater β, such as an exposure apparatus, a washing apparatus, a drying apparatus, and an inspection apparatus.
