Abstract
Systems and techniques for using a three-dimension (3D) resist profile aware etch-bias model are described. A 3D resist profile aware etch-bias model can be calibrated based on empirical data. Next, the 3D resist profile aware etch-bias model can be used in one or more applications, including, but not limited to, lithography verification, etch correction, optical proximity correction, and assist feature placement.
