Patent ID: 7340320

Claim:
An operation method of a recipe control process in which multiple processing targets are processed in sequence under conditions continuously in a processing apparatus using recipes that specify a set of control parameters specifying the processing conditions of processing targets, wherein the targets are each placed in numbered places prior to the processing, and different values of at least one control parameter are set for different targets processed in sequence, said method comprising: setting a reference value for the at least one control parameter; allocating the recipes to the numbered places in sequence, said recipes having the reference value for the at least one control parameter; specifying correction coefficients which lead to the different values of the at least one control parameter, respectively, by correcting the reference value for the at least one control parameter; applying the correction coefficients to the targets in sequence which are subjected to the processing; and performing the recipe control process for multiple processing targets by using the correction coefficients applied to the respective processing targets so as to apply in sequence the recipes having the different values of the at least one of the parameters to the respective processing targets.
