Method of manufacturing mask for conductive wirings in semiconductor device

Abstract

Disclosed is a method of manufacturing a mask for conductive wirings in a semiconductor device, wherein the conductive wirings are formed on a semiconductor substrate of the semiconductor device, comprising the steps of: (a) calculating data for the entire regions of the semiconductor substrate on which the conductive wirings are formed; (b) reading the size, shape and position of the conductive wiring patterns for the conductive wirings to generate data for conductive wirings, and storing the generated conductive wirings data; (c) extending the conductive wirings data by a predetermined size to generate data for the extended conductive wirings; (d) subtracting the extended conductive wirings data from the data for the entire regions of the semiconductor substrate to calculate a differential data between the extended conductive wirings data and the entire regions data, and to generate data for dummy conductive wiring pattern; (e) adding the conductive wirings data to the dummy conductive wiring pattern data to form a pattern the size and position of which correspond to data obtained by the addition operation on the mask by using a clear field method.
