| 摘要 |
A pattern decomposition and optical proximity correction method for double exposure comprises defining second exposure patterns by performing a logical operation on target patterns and first exposure patterns, comparing the first and second exposure patterns with the target patterns by performing a logical operation on the first and second exposure patterns, performing optical proximity correction on the first exposure patterns to form fourth exposure patterns, performing the optical proximity correction on the second exposure patterns to form fifth exposure patterns, and comparing the fourth and fifth exposure patterns with the target patterns by performing a logical operation on the fourth and fifth exposure patterns.
