Classification: CPC G | IPC G

Claim 0:
1. A non-transitory computer-readable medium holding computing device-executable instructions for process model calibration, the instructions when executed causing at least one computing device equipped with at least one processor to:
perform in a virtual fabrication environment a plurality of virtual fabrication runs for a semiconductor device based on a Design of Experiment (DOE) using 2D design data and a process sequence, the plurality of virtual fabrication runs building a plurality of 3D models;
receive a user identification of one or more targets for the plurality of 3D models;
receive, via a user interface in the virtual fabrication environment, a user selection of desired values for selected targets associated with one or more key parameters whose value affects measurement data for the one or more targets, wherein the key parameters are identified in the virtual fabrication environment by an analytics module using a regression algorithm that generates regression data;
receive a user selection of upper and lower bounds for each identified key parameter via the user interface in the virtual fabrication environment;
execute an optimization algorithm for the plurality of 3D models using the key parameters, desired values and upper and lower bounds, wherein the optimization algorithm performs indirect optimization using the regression data; and
display or export results from the optimization algorithm.
