Definitions
- the CPU 51 reads the control program stored in the ROM 52 to the RAM 53 and controls the driving of the film forming apparatus 1.
- a signal is input to the input I / F 55 from the reception unit 30 that receives a user operation such as a keyboard or a touch panel.
- the CPU 51 outputs a drive or stop signal to the source gas supply unit 5, the high frequency power supply 7, the plasma generation unit 11, the cleaning gas supply unit 12, and the vacuum pump 9 via the output I / F 56. Further, an open or close signal is output to the on-off valve 13 via the output I / F 56.
- the reaction chamber 2 is maintained at a predetermined pressure by driving the vacuum pump 9, and the source gas is supplied to the shower head 4 through the pipe 6 by driving the source gas supply unit 5.
- the high frequency power source 7 By driving the high frequency power source 7, a voltage is applied between the shower head 4 and the mounting table 3, and the plasma source gas adheres to the substrate 20, and a thin film is formed on the substrate 20.
- step S2 When 6 hours or more have elapsed since the time when the previous cleaning process or the continuous cleaning process was completed (step S2: YES), the CPU 51 outputs an open signal to the on-off valve 13 and opens the on-off valve 13 (step S3). Then, the CPU 51 outputs a drive signal to the cleaning gas supply unit 12 (step S4), and outputs a drive signal to the plasma generation unit 11 (step S5).
- the control part 50 comprises a temperature control part by performing the process of step S4 and S5.
- the plasma-ized cleaning gas is discharged together with substances such as gas remaining in the supply pipe 10.
- step S6 When the predetermined time has elapsed (step S6: YES), the CPU 51 outputs a stop signal to the cleaning gas supply unit 12 (step S7), and outputs a stop signal to the plasma generation unit 11 (step S8).
- the film forming apparatus 1 in a predetermined specification, when it is 6 hours or less, aluminum fluoride or the like in the supply pipe 10 can be discharged before the precipitation of particles becomes significant.
- the temperature of the supply pipe 10 becomes approximately 100 ° C. to 200 ° C.
- the time for maintaining the temperature for preventing the precipitation and the driving efficiency of the film forming apparatus 1 are taken into consideration, and 5 to 6 hours are set as threshold values. It is reasonable.
- a film for preventing the reaction chamber 2 from being etched may be formed in advance on the inner wall of the reaction chamber 2 before the continuous cleaning process is executed.
- the amount of the cleaning gas supplied to the plasma generation unit 11 may be smaller than the amount of the cleaning gas supplied in the cleaning process (normal cleaning process). In this case, the consumption amount of the cleaning gas in the continuous cleaning process can be reduced.
- the substance in the supply pipe 10 is discharged before the precipitation of particles becomes significant. can do.
- FIG. 4 is a schematic view schematically showing the configuration of the film forming apparatus 1.
- a heater 14 is provided around the supply pipe 10.
- a temperature sensor 15 is provided in the supply pipe 10.
- FIG. 6 is a flowchart for explaining the continuous cleaning process by the control unit 50. It is assumed that the CPU 51 stores the time when the cleaning process or the continuous cleaning process is completed in the storage unit 54 in the initial state. The vacuum pump 9 is assumed to be driven.
- the CPU 51 waits until a signal for starting the continuous cleaning process is received from the receiving unit 30 (step S21: NO).
- the CPU 51 takes in the signal from the temperature sensor 15 and determines whether or not the temperature of the supply pipe 10 is 100 ° C. or less (step S22). .
- the CPU 51 advances the process to step S26 described later.
