Detects a guideline for the time of failure other than the parts that are specified. This makes it possible to know in advance the guideline timing for bulb replacement so that the bulb will not be replaced after it breaks down during film formation. The details will be described below.
- valve opening / closing is determined by two threshold values, that is, a valve opening lower limit value as the first set value and a valve opening upper limit value as the second set value. These two threshold values (valve opening lower limit value, valve opening upper limit value) are preset in the storage device (storage unit) of the control unit 19a. However, since the pressure control controller 19b controls the valve opening in order to reach the target predetermined pressure, for example, the trace value of the valve opening as a result of executing the recipe by setup or the like is checked to open and close the valve.
- valve opening lower limit value and the valve opening upper limit value are configured to be configurable on the configuration screen displayed by the operation unit 19c included in the controller 19.
- the valve opening lower limit is greater than 0% and less than 50%, for example 20%
- the valve opening upper limit is greater than 50% and less than 100%, for example 80%.
- the valve opening lower limit is set so that the minute fluctuation value of the valve opening during pressure control falls within the range below the valve opening lower limit value. Determine the value.
- the opening / closing operation of a small swing width during the execution of pressure control is set so as not to be subject to the valve opening / closing count.
- the valve can be operated manually, and the control unit 19a can (always) collect data on the valve opening even when the recipe is not being executed.
- the control unit 19a When the control unit 19a receives the monitor value of the valve opening degree of the APC valve 15 from the pressure control controller 19b, the control unit 19a monitors the monitor value of the valve opening degree. For example, as shown in FIG. 2, when the monitor value of the valve opening transitions from the valve opening lower limit value or less to the valve opening upper limit value or more and further to the valve opening lower limit value or less, the control unit 19a valves. The count value of the number of times of opening and closing is counted up once. In short, the control unit 19a determines whether or not the valve is open / closed when the monitor value of the valve opening is the lower limit of the valve opening.
- the monitor value of the valve opening acquired during monitoring reaches the valve opening lower limit value after passing through the valve opening upper limit value. If the monitor values of all valve openings acquired during monitoring are less than the valve opening upper limit value, it is determined that the valves are not opened or closed. Then, when the determination of the open / closed state of the valve opening is completed, the monitor value of the valve opening monitored so far is cleared, and the monitoring of the valve opening is started.
- FIG. 3 will be described in more detail. In FIG. 3, when the monitor value of the valve opening degree reaches the valve opening degree lower limit value from less than the valve opening degree lower limit value, the control unit 19a starts determining whether or not the valve is opened or closed.
- valve opening degree monitoring may be started when the valve opening degree is less than the lower limit value, or when the valve is fully closed (the valve opening degree monitoring value is 0%).
- the control unit 19a determines that the valve is not opened / closed because the monitor value of the valve opening between the valve opening lower limit value is less than the valve opening upper limit value, and counts the number of valve opening / closing times. Do not upload. In other words, in the control unit 19a, the maximum value of the valve opening monitor value has reached the valve upper limit value by the time the valve opening monitor value rises from the valve opening lower limit value and returns to the valve opening lower limit value. If not, it is determined that the valve does not open or close. Therefore, the control unit 19a does not count up the number of times the valve is opened and closed.
- the control unit 19a is used in the section where the valve opening degree upper limit value or more is changed from less than the valve opening degree lower limit value and then the valve opening degree lower limit value is not lowered.
- the count value of the number of times the valve is opened and closed is not counted up. Therefore, even if the valve opening upper limit value is exceeded a plurality of times between the time when the valve opening monitor value exceeds the valve opening lower limit value and the time when the valve opening lower limit value is reached, the control unit 19a still opens and closes the valve. Since the count value of is not counted up, the number of times the valve is opened and closed is counted as one. Therefore, in the valve opening sequence as shown in FIG. 3, the valve opening upper limit value is exceeded twice, but since the control unit 19a determines whether or not the valve is opened or closed only once, the number of times the valve is opened or closed is counted. Is only once.
- valve opening and closing Since the number of valve opening and closing is counted by the operation between the opening degree of 0% (FULL CLOSE) and the valve opening lower limit value and the valve opening upper limit value of 100% (FULL OPEN), "FULL CLOSE” or “FULL CLOSE” or " It is possible to count the number of times a part (valve) that deteriorates is opened and closed even if it does not reach "FULL OPEN". Since the valve opening lower limit value is determined so that the valve opening fluctuation value during pressure control in the film forming recipe falls within the range below the valve opening lower limit value, for example, pressure control is performed in the film forming recipe. Even when the APC valve 15 is set to "FULL OPEN" from the inside and then the pressure is controlled in the film formation recipe, the number of times the valve is opened and closed can be counted.
- the control unit 19a determines the number of times the valve is opened and closed counted as described above by using the upper limit threshold value.
- the number of times before reaching the endurance number of times of the APC valve 15 is set as the upper limit value of the valve opening / closing number, and when the count value of the valve opening / closing number reaches the upper limit value, the user is notified of the valve replacement time by an alarm report.
- the upper limit of the number of times the valve is opened and closed is set to 10000 times, and an alarm is issued when the count value reaches 10000 during the execution of recipe 1 (Reciep1).
- the film forming recipe of Recipe 1 that is, the wafer discharge (Wafer D.CHG) after the boat unloading process is completed for the valve replacement work
- the film forming recipe of the next recipe 2 (Reciep2) is started. That is, the wafer charge (Wafer CHG) before the boat loading process is stopped, and an arbitrary process (for example, valve replacement) at the time of valve replacement can be executed.
- the upper limit of the number of times the valve is opened and closed is set as a guideline for the manufacturer's guaranteed value or a past example of the number of times the valve is opened and closed until failure.
- monitoring for determining whether or not the valve is opened or closed is started.
- the monitor value of the valve opening becomes equal to or higher than the upper limit value of the valve opening
- monitoring for determining whether or not the valve is opened or closed may be started.
- the monitor value of the valve opening reaches the lower limit of the valve opening, it is determined that the valve is open / closed, and the count value of the number of times the valve is opened / closed is counted up.
- the valve opening / closing number is set to 0 as the valve opening / closing number by the control unit 19a or the host controller. Can be done.
- the current value (Current Value), which is the monitor value of the number of times the valve is opened and closed, is set to 0 times (times) by the current value clear button.
- the control unit 19a or the host controller sets an arbitrary offset value to the valve opening / closing number of times.
- the current value (Current Value) button which is the monitor value of the number of times the valve is opened and closed, is set to 150 times (times). This function is used when replacing only the pressure control controller without replacing the APC valve used.
- the numerical value to be set (150 in this case) is, for example, the number of times the valve is opened and closed according to the present disclosure is calculated from the past recipes.
- the monitor value of the opening degree of the APC valve is performed while the pressure is controlled during the execution of the process recipe, but the present invention is not limited to this period and is performed during the execution of the process recipe. It may be performed all the time, or a step of the process recipe for monitoring the monitor value of the opening degree of the APC valve may be specified in advance, and the step may be performed in this specified step.
- the number of times the valve is opened and closed may be counted by the pressure control controller 19b instead of the control unit 19a.
- the guideline for replacing the APC valve is the valve opening / closing time, the area between the valve opening / closing times (the vertical axis is the gas flow rate when the valve is open, and the horizontal axis is the opening time). You may.
