    摘要: A method of forming assist feature patterns includes providing an original layout pattern having at least a first region defined therein, the first region having a first light transmission rate larger than 0%; performing a search step to the original layout pattern to define at least a second region having a second light transmission rate equal to 0% in the original layout pattern; forming a plurality of assist features in the second region to increase the second light transmission rate to larger than 0%; and outputting the original layout pattern and the assist features to a reticle blank.
