New LithoWorld Model Enhances Lithography Process Recovery Using SEM Data

Researchers have developed LithoWorld, a novel endpoint world model designed to recover lithography process windows using scanning electron microscopy (SEM) data. This model aims to correct patterns that drift outside their acceptable parameters, ensuring qualified SEM morphology. LithoWorld utilizes a causal predictive branch for feature alignment and a conditional flow policy for generating corrections, achieving an 88.5% success rate in qualifying regions on test data, outperforming existing methods.
