Abstract

A method of manufacturing semiconductor wafers using a simulation tool to determine a set of predicted wafer electrical test measurements that are compared to a set of target wafer electrical test measurements to obtain a set of optimized process parameters for the equipment for the next process. The optimized process parameters are compared to the equipment characteristics for the equipment of the next process and the process parameters for the next process are automatically adjusted.
