- control section 7 includes a wafer arrangement layout determining section 77.
- the wafer arrangement layout determining unit 77 is a storage unit in which an algorithm for determining an arrangement layout of a product substrate in each batch size is described. For example, when the product is to be fully loaded with 25 product wafers, the wafer port 27 usually has 29 steps of holding grooves (slots). According to the above algorithm, when the uppermost stage is the first stage, the product wafers PW are arranged around the 15th stage, the motor wafers MW are arranged above and below the product wafers PW, and the dummy wafers are arranged above and below them. C DW is deployed. FIG.

- the control unit 7 includes a counter 81, a wafer W transfer means 3 described in FIG. 1, a temperature controller 51 (51 a to 51 e), and a flow rate adjustment unit 65, 6 6 is connected.
- the counter 81 is, for example, a product wafer in the carrier C on the carrier loading / unloading unit 21 based on a signal from a mapping sensor (not shown) such as a reflection type optical sensor provided in the carrier loading / unloading unit 21. Count the number of sheets.
- the control unit 7 knows where to place the carrier C in the carrier stop force 23 and when to perform the heat treatment.
- carrier loading If the number of product wafers in each carrier C at the time of being carried into the outlet 21 is counted, the number of product wafers to be heat-treated in each batch process can be ascertained. However, in actuality, information on how many product wafers are loaded into the carrier C is sent from the control unit or the upper-level computer in the previous process to the vertical heat treatment apparatus, so the wafer count by the matching sensor is counted. Even without performing, the number of wafers in each carrier C can be grasped. However, it is more reliable to use both the wafer count and the information transmitted. Note that the operator can also input the batch size via the input unit 74.
- the carrier C is loaded into the carrier loading / unloading section 21 from the outside (step S1).
- a corresponding recipe is selected from the recipe selection unit 73 via the input unit 74 according to the processing type (step S2).
- the number of product wafers PW in the carrier C is counted by the counter 78, and the number information is taken into the control unit 7. Based on the number information, the batch size of the heat treatment to be performed is grasped (step S3).
- the CPU 71 obtains the flow rate of the processing gas corresponding to the batch size by referring to the batch size-flow rate relationship data in the first storage section 75 in accordance with the program in the program storage section 72.
- the temperature gradient (the target temperature value of each zone 1 to 5) corresponding to the batch size is obtained by referring to the batch size-temperature relationship data in the storage unit 76 of Step 2 (Step S4).
- the wafer arrangement determining unit 77 determines the arrangement layout of the product wafer, dummy wafer, and monitor wafer corresponding to the batch size (step S5).
- the CPU 71 outputs a control signal to a controller (not shown) to control the transfer unit 3 according to the program in the program storage unit 72 so that the determined layout rate is obtained.
- the wafer W is transferred to the wafer boat 27 (Step S6). After that, the wafer boat 27 is carried into the reaction vessel by the boat elevator 26.
- step S7 dichlorosilane and ammonia gas are respectively supplied into the reaction vessel from the processing gas supply pipe 6 (61, 62) under a predetermined pressure and temperature, and heat treatment is performed on the wafer W to form a silicon nitride film.
- the film is formed (step S7). That is, The heat treatment is performed based on the steps and parameter values described in the selected recipe. Therefore, regarding the flow rate of the processing gas, the control signal is output to the flow rate control units 65 and 66, and the flow rate is adjusted so as to be a flow rate according to the batch size.
- the control signal is output to the temperature controller 51 (51a to 51e), and the temperature of the heater 5 (5a to 5e) is adjusted so that the temperature is in accordance with the patch size. Controlled. After the heat treatment for a predetermined time, the wafer boat 27 is carried out of the reaction vessel (Step S8).
- the heat treatment is not always performed with the wafer boat 27 fully loaded with wafers W, but the flow rate parameter of the processing gas according to the number of product wafers to be processed in one batch (this example) In this case, heat treatment is performed according to the total flow rate target value). Therefore, no dummy substrate is required for full loading, and the cost can be reduced. Also, a decrease in throughput can be suppressed.
- the target value of the flow rate parameter is determined so that the film formation rate is uniform between batch processes in which the number of product wafers to be processed in one patch is different from each other. Regardless, the quality of the thin film is uniform between batches. In other words, the film quality may be changed by changing the flow rate, but it is considered that the film quality is preserved by changing the flow rate after preserving the deposition rate. More specifically, the deposition rate is determined by the temperature of the wafer and the gas environment near the wafer. Therefore, even if the flow rate is changed, the fact that the film formation rate is the same at the same temperature means that the gas environment near the wafer is the same. If the temperature of the wafer and the gas environment are the same, the quality of the formed thin film is considered to be constant. Therefore, even if the circuit pattern of the device becomes finer and thinner, the variation in device characteristics can be suppressed.
- a film thickness per unit flow rate in the total flow rate that is, a sensitivity coefficient (nm / sccm) is previously determined, and a film thickness of the monitor wafer after the heat treatment is measured, and the film thickness is allowed.
- the difference in film thickness is divided by the sensitivity coefficient to obtain a corresponding increase or decrease in the flow rate, and the flow rate may be adjusted by the increase or decrease.
- the deposition rate (sensitivity coefficient) per unit flow rate in the total flow rate is determined in advance, and the deposition rate of the obtained thin film is out of the allowable deposition rate. This is essentially the same as modifying the flow rate based on the difference and the sensitivity coefficient when the flow rate is being adjusted.
- FIG. 8 shows an example of the configuration of the control unit 7 for implementing such a method.
- a flow parameter correction unit 79 is a unit that corrects the flow based on the sensitivity coefficient and the difference between the input film thickness measurement value and the allowable film thickness value. After the flow rate is corrected, heat treatment is performed at the corrected flow rate. Further, as shown in FIG. 8, it is preferable that the thickness measurement value from the thickness measurement unit 8 is input to the control unit 7 online. In this case, the steps of calculating the difference between the measured film thickness and the predetermined allowable film thickness, calculating the flow rate correction based on the sensitivity coefficient, and correcting the flow rate are automatically performed. obtain. It is thought that the monitor wafer will have a thin film equivalent to the product wafer. Therefore, correcting the flow rate based on the measured thickness of the monitor wafer is equivalent to correcting the flow rate based on the measured thickness of the product wafer. The flow rate may be corrected based on the film thickness of the product wafer instead of the monitor wafer.
- the flow rate parameter is not limited to the total flow rate where the flow rate ratio between the two gases is constant, for example, when two kinds of film forming gases are used.
- the flow parameter may be a flow ratio with a constant total flow, or both a flow ratio and a total flow.
- the flow parameter may be a flow ratio between the carrier gas and the film forming gas, or a plurality of kinds of film forming gases when the flow rate of the carrier gas is constant. May be used.
- the present invention is not limited to the process of forming a thin film by CVD or the like, but can be applied to, for example, a case where an oxide film is formed by oxidizing a silicon film.
