Abstract:
1. A semiconductor manufacturing method comprising: a first step of inputting a target thickness value of a product model processed with thermal oxidization into a host computer; a second step of transmitting a current atmospheric pressure obtained from a barometer and comparative data to the host computer, the comparative data including an oxidization time and an average thickness value of a preceding processed lot in the same oxidization process as the product model; a third step of calculating by the host computer a time for desired oxidization processing by adding a first correction value obtained from a difference between the target thickness value and the average thickness value of a preceding processed lot and a second correction value obtained from a difference between the current atmospheric pressure and an atmospheric pressure at the time of processing the preceding lot; and a fourth step of transmitting the calculated time for the desired oxidization processing to an apparatus for performing a thermal oxidization process.
