The invention provides a post-optical proximity correction repair method which includes the steps of: 1) forming a local correction region on the basis of an error mark generated in an optical proximity correction process before the post-optical proximity correction repair; and 2) performing local optical proximity correction in the local correction region until no error mark is generated. The post-optical proximity correction repair method performs the post-optical proximity correction on the basis of the local correction region, thereby greatly reduces operation load and improves efficiency.
