Abstract

A method of optimizing a lithographic process for semiconductor fabrication includes determining that a semiconductor wafer experienced a photoresist exposure delay. At least one operating parameter of a post exposure baking process is adjusted based on the semiconductor wafer having experienced the photoresist exposure delay. The post exposure baking process is performed on the semiconductor wafer utilizing the adjusted at least one operating parameter.
