Description
Technical field
The present invention relates to a kind of chip container, particularly relate to a kind of sealable wafer enclosure, on door, have latching member mechanism with door.
Background technology
In order to seal wafer in container, the professional has adopted several different methods.For storing and transporting wafer, some containers have rigid body, have to be used to hold the groove that vertically is provided with of wafer and have flexible snapping lid on rigid body.These containers are not suitable for the wafer that can not be exposed to ambient atmosphere usually.
For range of sizes is 200mm or littler wafer, adopt the container 20 that is commonly referred to SMIF (normalisation mechanical connecting device) shown in Fig. 1, so that the microenvironment of clean seal is provided, this environment can make wafer transport enter Fabricating machinery, and wafer is exposed under the ambient atmosphere condition.From U.S. Pat-4,532, can see the embodiment of these containers in 970 and US-4,534,389.This SMIF container adopts transparent container part 34 usually, wherein has the door bracket part 35 that is positioned at the below, and the structure of described door bracket part 35 also has lockable door 36 as the flange that is arranged on open bottom 52, seals and open the bottom by door 36.The door holder part 35 can be clamped on the Fabricating machinery, the door fix in position on the Fabricating machinery in below the SMIF container door on.Two doors can be in housing enters sealing processing environment the described Fabricating machinery simultaneously downwards.H shape vehicle 38 separately is positioned on the top surface 40 of SMIF container door 36, and is mounted with wafer, and vehicle and container are downward, so that use and process described wafer.
Semiconductor machining industry has developed towards utilizing large batch of wafer, particularly is of a size of the wafer of 300mm.By the development of industrial standardization technology, adopt the conveying assembly of this wafer, can utilize the door of opening previously, this door lands downwards from conveying assembly.With reference to accompanying drawing 2, wherein described this closure member of opening previously.This closure member has the similar element in the part 34 in container, not extensible vehicle separately.
The conventional door closure member that is used for salable closure member and the structure of locking mechanism are that prior art is known.Usually, these representative type structures have shortcoming, promptly are not easy dismounting, have many moving-members, and adopt metal parts to comprise fastener.In semiconductor wafer vehicle and container, do not wish to adopt metal fastenings or other metal partss.Metal parts can produce the destruction particle of a large amount of scratches or scratch wafer.Employing metal fastenings stack-mounted conveying assembly can produce scratch or the scratch to wafer.Therefore, need avoid in wafer enclosure, using metal fastenings or other metal parts.
Though closure member as described above is used for suitable clean environment, in long-time, in closure member, the closure member inside at the door that needs all the time to clean can accumulate pollutants.This pollutants can produce by the friction between the parts, and for example, the locking mechanism of operated door produces as mentioned above, produce by loading or unloading wafer on chip support, and by producing at container part installation or removal door.Because parts are many in the locking mechanism of routine, for the dismounting door causes difficulty, owing to use metal fastenings to be difficult to this door of cleaning.Therefore wish very much a kind of can the easy-off door, it has the easy-off locking mechanism, and has minimum moving-member.
Need bigger door for bigger wafer carrier, locking mechanism need be fixed in the door.Under perfect condition, the physical structure of this closing means is simple, has a spot of movable parts, and does not have metal parts.
Recently, the conveying assembly of opening previously is developed, and it can satisfy requirement recited above basically.For example with reference to the proprietary U.S. Pat-5,915 of authorizing Nyseth, Krampotich and the present patent application, 562.And with reference to 08/904, No. 660 application, the income expense has been paid Eggum, Wiseman, and Mikkelsen, Adams, Bores, and assign in everyone of the present patent application.U.S. Pat-5,915,562 and 08/904, No. 660 applications in this article as a reference.These locking mechanisms, and the locking mechanism of other wafer carrier is known in the prior art, wherein adopts rotary cam member usually.These cam member representative types are formed by common round plastic dish, have the microscler sunk part that constitutes cam face.
This locking mechanism is closed in the closure member of door in the vehicle of prior art.This closure member is isolated usually, has wherein comprised many particles that produced by locking mechanism.These particles can accumulate, and ultimate demand is removed or is cleaned.In the conventional mode, comprise that the wafer carrier of chip container need adopt the aqueous system to clean, and adopt pressurized air or gas to carry out drying.This clean operation is the key link that keeps production in enormous quantities.In order to finish clean operation effectively, need to remove door or take off lid at least, to expose locking mechanism.This operation labour intensity is high and dull.Want not take off that lid cleans inside is very difficult.And, be in the osed top locking mechanism, to finish if clean, dry osed top locking mechanism also to have a lot of problems.

This locking mechanism also can utilize handle also can rotate the in-to-in cam member by manual operation.Traditional 300mm wafer transfer device has this manned handle, and it needs in two handles each, so that separately rotate, then by the artificial handle of pulling, by manually taking off door.This rotational motion that is separated by each hand of operator is asymmetric and clumsy, the action of normally violating the human body intuition.In addition, be difficult to know whether each turning handle has rotated complete atresia or the needed revolution of unblanking fully.
Though, this rotary cam member can wafer carrier the door in the generation effect, still exist some shortcomings.This rotary cam member is difficult to design and makes, and needs sizable circular cam element usually, so that rational mechanical efficiency is provided.Reduce the size of this cam member, will reduce mechanical efficiency.In addition, when rotational motion was converted into straight-line motion, cam member can not smooth running, and this irregular movement can not be applicable to locking and unblank.Particularly, when these rotary cam members of artificial rotation, before latch portion is fully extended or return, unexpected stop motion may appear.
In addition, this rotary cam member is unfavorable for providing the locking/unlocking handle of additional nonrotational artificial grasping.Suppose that the auxiliary handle that rotates is known.But the rotation of this handle provides very unsettled handling device, and it causes steadily and heavy not moving and take out door from closure member door opening partly.This jiggly operation may cause door to contact with the opening accident of closure member at door, produces thus and scratches particle, damages the wafer in the container, occurs particle in wafer carrier, other bad results perhaps occur.Door with chip container of locking mechanism should have grasps handle ideally, so that the locking mechanism under the nonrotational condition of manual operation.
Therefore, need a kind of manned door, it can be steadily, easily operate according to intuition, and have simple physical construction.In addition, need this door to meet industrial standardization, so that opposite house carries out automation mechanized operation.
