- a ruthenium film is also formed on the reaction vessel (reaction tube 1 and manifold 11), wafer boat 2, and heat retention unit 22. Since the ruthenium film has a property of reflecting light as described above, it is preferable to perform cleaning, for example, every time the film formation process is performed, in order to stabilize the processing temperature of the wafer. Therefore, for example, the following cleaning process is performed.
- the inside of the reaction tube 1 is maintained at, for example, about 300 ° C., and the wafer boat 2 is loaded into the reaction vessel without mounting the wafer W, and is evacuated to a predetermined degree of vacuum.
- the power supplied to the heater 3 is increased, and the temperature inside the reaction tube 1 is raised to, for example, 1000 ° C., and the valve V 2 is opened to supply oxygen gas, which is a cleaning gas, to the reactor for example.
- oxygen gas which is a cleaning gas
- the pressure in the reaction vessel is adjusted to, for example, 13 pa (1 Torr) to 13.3 Kpa (10 O Torr) by the pressure adjusting unit 14.
- This state is maintained for a predetermined time and the cleaning process is performed.
- the time for this process depends on the thickness of the ruthenium film formed on the wafer W and the cleaning cycle (the number of film forming processes before cleaning). For example, a ruthenium film with a target of 20 nm is formed on the wafer W. In this case, a cleaning process is performed, for example, for 20 minutes each time the film is formed.
- FIG. 2B is a diagram showing a state in which the ruthenium film 72 is removed by oxygen gas.
- Ru02 (solid) 73 is generated on the inner wall surface of the reaction vessel.
- the Ru 02 (solid) becomes Ru 04 (gas) and sublimates, thereby cleaning the ruthenium film 72.
- the reaction tube 1 is used as in the case of using C 1 F3 gas. Also, there is no problem that quartz products such as the wafer port 2 are damaged, and that chlorine and fluorine adhere to the inner wall of the reaction tube 1 and are taken into the ruthenium film. As is clear from the examples described later, cleaning can be performed in a short time because cleaning is performed in a high-temperature atmosphere of 850 ° C. or more and a reduced-pressure atmosphere of 1.33 Kpa. High equipment operation efficiency can be obtained.
- the pressure in the reaction tube was set to 1.33 Kpa, and the temperature during cleaning (when supplying oxygen gas) was varied to evaluate the amount of ruthenium film removed.
- the cleaning time was set to 30 minutes in each case.
- the amount of ruthenium film removed was evaluated by irradiating the ruthenium film on the wafer before and after cleaning with X-rays, respectively, and determining the ruthenium film from the intensity of X-rays corresponding to the energy of ruthenium among the fluorescent X-rays reflected from the ruthenium film.
- the amount of the film removed by cleaning is determined from the difference in the amount of ruthenium film before and after cleaning. The results are as shown in FIG. However, in FIG.
- the amount of ruthenium film removed increases with increasing temperature. This is probably because the higher the temperature, the faster the reaction rate described in FIGS. 2A to 2C.
- the inventor has determined that if the difference in received light intensity is 1.5 kcps, the operation efficiency of the device is sufficiently high. The reason is that if the difference in received light intensity is 1.5 kcps, the removal rate of the ruthenium film can be as high as about 3.6 nmZ, which is a very high removal rate. Looking at the results in Fig. 3, if the temperature is 850 ° C or higher, the difference in the received light intensity is 1.5 kcps or more even for the upper wafer where the ruthenium film removal rate is low. Should be 850 ° C or higher.
- the temperature of 850 ° C or higher in the reaction tube 1 means that the area where the ruthenium film to be cleaned adheres is 850 ° C or higher, and in the above example, the inner tube 1 This means that the temperature of the inner wall of a is 850 ° C or more.
- the ruthenium film adheres to the upper part of the outer tube 1b, but does not adhere to the lower part because a purge gas (not shown) flows during the process.
- the removal amount of the ruthenium film increases as the temperature rises, so it is not particularly necessary to keep the temperature below this temperature, but it may be decided according to the policy of each site, From this experimental result, it is considered that cleaning can be performed with considerably high efficiency if the temperature is set to 900 ° C, for example.
- the temperature inside the reaction tube was set to 850 ° C, and the pressure during cleaning (when supplying oxygen gas) was set to 133 pa (lTorr), 1.33 Kpa (10 Torr) s, and 13.3 Kpa (10 Torr).
- the amount of ruthenium film removed was evaluated by setting.
- the cleaning time was set to 30 minutes in each case.
- the amount of ruthenium film removed was evaluated by the same method as described above. The results are as shown in FIG. As can be seen from Fig. 4, the removal amount of the ruthenium film increases as the pressure decreases, which is presumably because the lower the pressure, the faster the volatilization of Ru-4. From the results in Fig.
- the pressure If the force is 1.33 Kpa or less, the difference in the received light intensity is 1.5 kcps or more even for the upper wafer where the ruthenium film removal rate is low, so the pressure condition is 1.33 Kpa.
- the pressure may be lower than the pressure. Also, the lower the pressure, the greater the removal of the ruthenium film, so the pressure does not have to be lower.
- the temperature inside the reaction tube was set at 850 ° C., the pressure was set at 1.33 Kpa, and the removal amount of the ruthenium film was evaluated by changing the flow rate of oxygen gas.
- the cleaning time was set to 30 minutes in each case.
- the amount of ruthenium film removed was evaluated in the same manner as described above. The results are as shown in FIG. Found that the removal amount of the ruthenium film increases as the flow rate of the oxygen gas from the results of FIG. 5 increases, the flow rate of the oxygen gas in the apparatus described above is at least 0. 2 c oxygen it can be seen that may be a sLm
- the appropriate flow rate of the gas depends on the size of the reaction tube, etc., and is determined by conducting experiments in advance for each device.
- the film to be cleaned in the present invention is not limited to the ruthenium film, but may be a ruthenium oxide film (Ru02).
- the ruthenium oxide film is formed on the wafer W by supplying oxygen gas into the reaction vessel in addition to the vapor of the Ru (EtCP) 2 liquid.
- This ruthenium oxide film can also be cleaned with oxygen gas in the same reduced-pressure atmosphere and high-temperature atmosphere as described above.
- an active oxygen gas may be used as the cleaning gas.
- the active oxygen gas for example, 03 gas, 0 * (oxygen radical) and OH * (hydroxy radical) can be used.
- a gas containing at least one of these can be used. it can.
- hydrogen gas and oxygen gas may be separately introduced into the reaction vessel and burned under a reduced pressure atmosphere, and 0 * and OH * generated in the burning process may be used.
- FIG. 6 shows that a plasma generator 81 for applying a high voltage to a gas to generate a plasma is provided outside the reaction vessel, and the plasma generator 8 is supplied from an oxygen gas supply source 82 via a flow rate controller 83.
- the oxygen gas sent to 1 is turned into plasma to generate a gas containing 0 *, which is supplied into the reaction vessel through a gas supply pipe 8 so that the ruthenium film is removed.
- active oxygen is used in this manner, cleaning of the ruthenium film can be performed at a lower temperature than when no oxygen gas is activated.
- the reaction container when cleaning the inside of the reaction container after forming the ruthenium film or the ruthenium oxide film on the object to be processed, the reaction container is not damaged and the object is not damaged. Cleaning can be performed efficiently without contaminating the processing object.
