Abstract:
A method of manufacturing a semiconductor device comprising:exposing a photo sensitive film formed on a conductive film through a medium of a reticle designed by generating main patterns and first dummy patterns separated with intervals from the main patterns, dividing each of said first dummy patterns into a plurality of spaced apart second dummy patterns, measuring each of said second dummy patterns to find third dummy patterns having respective widths and areas below respective smallest allowable values, and connecting respectively each third dummy pattern which is adjacent to a second dummy pattern with the adjacent second dummy pattern by generating a connecting dummy pattern; developing the exposed photosensitive film thereby to form an etchant-resistant mask in conformity with said main patterns and said dummy patterns; and removing by etching said conductive film with said etchant-resistant mask thereby to form an interconnection layer and a dummy layer.
