Abstract:
A method for fabricating a phase shift mask includes preparing a transmissive substrate on which a first mask region and a second mask region surrounding the first mask region are defined. In the first mask region, main patterns are formed having a first pitch in a first direction and a second direction perpendicular to the first direction. Each of the main patterns has a first area. In at least one row, assist patterns are formed at the first pitch to surround the main patterns. Each of the assist patterns has a second area less than the first area. In the second mask region, dummy patterns are formed in a plurality of rows. The dummy patterns surround the assist patterns at the first pitch. Each of the dummy patterns has a third area greater than the first area.

Claim (Index 5):
The method as claimed in  claim 1 , wherein:\n four boundary lines are virtually formed by connecting centers of dummy patterns adjacent to the assist patterns, from among the dummy patterns, and from among the four boundary lines, two boundary lines facing each other in the first direction are straight lines and two boundary lines facing each other in the second direction are waveforms.
