COMPUTER-IMPLEMENTED METHODS, STORAGE MEDIUM, AND SYSTEM FOR CREATING A METROLOGY TARGET STRUCTURE DESIGN FOR A RETICLE LAYOUT

摘要

Computer-implemented methods, carrier media, and systems for creating a metrology target structure design for a reticle layout are provided. One computer-implemented method for creating a metrology target structure design for a reticle layout includes simulating how one or more initial metrology target structures will be formed on a wafer based on one or more fabrication processes that will be used to form a metrology target structure on the wafer and one or more initial metrology target structure designs. The method also includes creating the metrology target structure design based on results of the simulating step.
