摘要
A method for decomposing a target circuit pattern containing features to be imaged into multiple patterns. The process includes the steps of separating the features to be printed into a first pattern and a second pattern; performing a first optical proximity correction process on the first pattern and the second pattern; determining an imaging performance of the first pattern and the second pattern; determining a first error between the first pattern and the imaging performance of the first pattern, and a second error between the second pattern and the imaging performance of said second pattern; utilizing the first error to adjust the first pattern to generate a modified first pattern; utilizing the second error to adjust the second pattern to generate a modified second pattern; and applying a second optical proximity correction process to the modified first pattern and the modified second pattern.
