Abstract

A virtual fabrication environment for semiconductor device structures that includes the use of virtual metrology measurement data to optimize a virtual fabrication sequence is described. Further, calibration of the virtual fabrication environment is performed by comparing virtual metrology data generated from a virtual fabrication run with a subset of measurements performed in a physical fabrication environment. Additionally, virtual experiments conducted in the virtual fabrication environment of the present invention generate multiple device structure models using ranges of process and design parameter variations for an integrated process flow and design space of interest.
