Classification: CPC B | IPC B

Claim 19:
20. A computer program product for controlling a semiconductor processing system, the computer program product residing on a non-transitory computer readable medium, the computer program product comprising instructions for causing one or more computers to:
receive from an in-situ monitoring system, for each region of a plurality of regions on a substrate being processed by a processing system, a sequence of characterizing values for the region;
for each region, determine a rate of change of the characterizing value for the region; and
calculate an adjustment for at least one processing parameter, wherein calculation of the adjustment includes minimizing a cost function that includes, for each region, a difference between a current characterizing value or an expected characterizing value at an expected endpoint time and a target characterizing value for the region, and wherein optimization of the cost function is subject to at least one constraint.
