    摘要: An optical proximity correction method for rectifying pattern on negative photoresist. Line pattern of integrated circuit is divided into L-shape regions or T-shaped regions. The L-shaped or T-shaped regions are further dissected into rectangular patches. Area of each rectangular patch is suitably reduced and reproduced onto a photomask. The photomask is used to form a corrected photoresist pattern.
