Disclosed is a method of setting a process parameter for use in manufacturing a semiconductor integrated circuit, comprising correcting a first pattern by using process parameter information to obtain a second pattern, the first pattern being one which corresponds to a design layout of the semiconductor integrated circuit, predicting a third pattern by using the process parameter information, the third pattern being one which corresponds to the second pattern and which is to be formed on a semiconductor wafer in an etching process, obtaining an evaluation value by comparing the third pattern with the first pattern, determining whether the evaluation value satisfies a preset condition, and changing the process parameter information when the evaluation value is found not to satisfy the preset condition.

Disclosed is a method of manufacturing a photo mask comprising preparing mask data for a mask pattern to be formed on a mask substrate, calculating edge moving sensitivity with respect to each of patterns included in the mask pattern using the mask data, the edge moving sensitivity corresponding to a difference between a proper exposure dose and an exposure dose to be set when a pattern edge varies, determining a monitor portion of the mask pattern, based on the calculated edge moving sensitivity, actually forming the mask pattern on the mask substrate, acquiring a dimension of a pattern included in that portion of the mask pattern formed on the mask substrate which corresponds to the monitor portion, determining evaluation value for the mask pattern formed on the mask substrate, based on the acquired dimension, and determining whether the evaluation value satisfies predetermined conditions.

An automated wiring pattern layout method is provided. With this method, a first wiring pattern is generated with width W and extending in a first direction, and a second wiring pattern is generated with width W and extending in a direction perpendicular to the first wiring pattern in a manner such that the end thereof ends at the end portion of the first wiring pattern. Moreover, an overlapping region is generated by bending an end of either one of the first or the second wiring pattern at a right angle to produce an L-shaped extension and overlaying the first and the second wiring pattern, and a rectangular-shaped VIA pattern is generated at the overlapping region.
