PROCESS-MODEL GENERATION METHOD, COMPUTER PROGRAM PRODUCT, AND PATTERN CORRECTION METHOD

摘要

A process-model generation method according to an embodiment of the present invention comprises: forming a test pattern on a film to be processed by exposing a test mask having a mask pattern formed thereon; generating a plurality of process models having a different model parameter; performing a simulation of the mask pattern by using each of the process models to predict a plurality of model patterns; calculating a difference in dimension between the test pattern and each of the model patterns; extracting a model pattern in which the difference in dimension from the test pattern is within a scope of specification from the model patterns; and specifying the process model, which predicts the extracted model pattern, as the mask pattern.
