摘要： In accordance with a set temperature profile including: a first step in which a temperature is varied from a first temperature to a second temperature during a first time period; a second step in which the temperature is maintained at the second temperature during a second time period; and a third step in which the temperature is varied from the second temperature to a third temperature; a substrate is subjected to a film deposition process. The first temperature, the second temperature, and the third temperature are determined based on the first relationship between temperature and film thickness, the measured film thicknesses at the plurality of positions, and a predetermined target film thickness. There are calculated expected film thicknesses at a plurality of positions on a substrate to be actually processed in accordance with the set temperature profile corresponding to the determined first temperature, the determined second temperature, and the determined third temperature. When the expected film thicknesses at the plurality of positions are not within a predetermined allowable range with respect to the predetermined target film thickness, at least one of the first time period, the second time period, and the third time period is varied.
