Abstract:
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 entire regions of the semiconductor substrate on which the conductive wirings are formed; (b) reading size, shape and position of 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 extended conductive wirings; (d) subtracting 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 having a size and a position of which correspond to data obtained by an addition operation on the mask by using a clear field method.
