Abstract:
Computer-implemented methods of optimizing a process simulation model that predicts a result of a semiconductor device fabrication operation to process parameter values characterizing the semiconductor device fabrication operation are disclosed. The methods involve generating cost values using a computationally predicted result of the semiconductor device fabrication operation and a metrology result produced, at least in part, by performing the semiconductor device fabrication operation in a reaction chamber operating under a set of fixed process parameter values. The determination of the parameters of the process simulation model may employ pre-process profiles, via optimization of the resultant post-process profiles of the parameters against profile metrology results. Cost values for, e.g., optical scatterometry, scanning electron microscopy and transmission electron microscopy may be used to guide optimization.

Claim (Index 30):
The method of  claim 1 , wherein:\n the computationally predicted result generated in (c) comprises a sequence of geometric profiles or profile parameters of a substrate feature computed from the configured process simulation model and corresponding to a sequence of times representing different durations of a substrate subtractive process or a substrate additive process; and the metrology result of (d) comprises a sequence of geometric profiles or profile parameters of the substrate feature obtained from experimental measurements of a substrate at the different durations of the substrate subtractive process or the substrate additive process.
