The method includes receiving an IC design layout; performing optical proximity correction (OPC) process to the IC design layout to produce a corrected IC design layout; and verifying the corrected IC design layout using a machine learning algorithm. The post OPC verification includes using the machine learning algorithm to identify one or more features of the corrected IC design layout; comparing the one or more identified features to a database comprising a plurality of features; and verifying the corrected IC design layout based on labels in the database associated with the plurality of features."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of post optical proximity correction (OPC) printing verification by machine learning","description":"Implementations of the disclosure provide a method of fabricating an integrated circuit (IC).
