Patent ID: 7930059

Claim:
A semiconductor manufacturing method in a thermal processing apparatus comprising a heater for heating an interior of a process chamber to process a substrate, a first thermometer for detecting a temperature in the process chamber, and a second thermometer for detecting a temperature in the process chamber, the second thermometer being arranged in a position closer to the heater than the first thermometer, the semiconductor manufacturing method comprising: a determination of, when the heater is controlled using a first output control pattern which includes an output amount by integral operation, an output amount by differential operation, and an output amount by a proportional operation in order that a temperature detected by the first thermometer becomes a target temperature from a temperature at a ramp-up start time, patterning at least a part of an operation amount of the heater by using a first heat amount to determine a second output control pattern, the first heat amount being obtained by subtracting an output amount based on the proportional operation from a second heat amount, the second heat amount being determined based on a temperature detected by the second thermometer and being defined at a period from the ramp-up start time to a time of maximum temperature, the operation amount of the heater being defined at the period; and a processing of processing the substrate while controlling the heater by using the second output control pattern.
