ABSTRACT:
Densely disposed patterns constituting a semiconductor integrated circuit device are divided into a first mask pattern and a second mask pattern28B such that a phase shifter S can be disposed, and a predetermined pattern is transferred on a semiconductor substrate by multiple-exposure thereof. The second mask pattern28B has a main light transferring pattern26c1, a plurality of auxiliary light transferring patterns26c2disposed thereabout, and a phase shifter S disposed in the main light transferring pattern26c1. The auxiliary light transferring patterns26c2are disposed such that respective distances from a center of each thereof to a center of the main light transferring pattern26c1are substantially equal. With this arrangement, a densely disposed pattern is transferred with sufficient process transfer margin.
