Abstract: A pattern decomposition method including following steps is provided. A target pattern is provided, wherein the target pattern includes first patterns and second patterns alternately arranged, and the width of the second pattern is greater than the width of the first pattern. Each of the second patterns is decomposed into a third pattern and a fourth pattern, wherein the third pattern and the fourth pattern have an overlapping portion, and a pattern formed by overlapping the third pattern and the fourth pattern is the same as the second pattern. The third patterns and the first pattern adjacent to the fourth pattern are designated as first photomask patterns of a first photomask. The fourth patterns and the first pattern adjacent to the third pattern are designated as second photomask patterns of a second photomask.

Abstract: A method of forming a photomask is provided. A first layout pattern is first provided to a computer system and followed by generating an assist feature pattern by the computer system based on the first layout pattern and adding the assist feature pattern into the first layout pattern to form a second layout pattern. Thereafter, an optical proximity correction process is performed with reference to both the first layout pattern and the assist feature pattern to the second layout pattern without altering the assist feature pattern to form a third layout pattern by the computer system. Then, the third layout pattern is output to form a photomask.
