A method for correcting layout pattern is disclosed. The method includes the steps of: providing a layout pattern having at least one segment; forming a rule-checking rectangle from the segment, wherein the rule-checking rectangle comprises at least one square; verifying whether the square of the rule-checking rectangle overlaps other layout pattern; removing the portion of other layout pattern overlapped by the square to obtain a corrected layout pattern; and outputting the corrected layout pattern to a mask.
