Abstract: A method of correcting a layout pattern is provided in the present invention. The method includes the following steps. A layout pattern including at least two adjacent rectangular sub patterns is provided. The layout pattern is then input into a computer system. An optical proximity correction including a bevel correction is then performed. The bevel correction includes forming a bevel at a corner of at least one of the two adjacent rectangular sub patterns, wherein the bevel is formed by chopping the corner, and moving the bevel toward an interaction of two neighboring segments of the bevel if a distance between the bevel and the other rectangular sub pattern is larger than a minimum value. The angle between a surface of the bevel and a surface of the rectangular sub pattern is not rectangular. The layout pattern is output to a mask after the optical proximity correction.

Abstract: A method for fabricating minimal fin length includes the steps of first forming a fin-shaped structure extending along a first direction on a substrate, forming a first single-diffusion break (SDB) trench and a second SDB trench extending along a second direction to divide the fin-shaped structure into a first portion, a second portion, and a third portion, and then performing a fin-cut process to remove the first portion and the third portion.

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.
