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 8):
A method for fabricating a semiconductor device, the method comprising:\n forming a material layer on a semiconductor substrate on which a cell region and an outer region surrounding the cell region are defined; sequentially forming a mold layer and a support forming layer on the material layer; forming a plurality of holes exposing the material layer by etching the mold layer and the support; forming a plurality of lower electrodes by applying a conductive material onto an inner wall of the plurality of holes; and etching the support forming layer to form a plurality of open regions and forming a support connecting the plurality of lower electrodes using a photolithography process using a phase shift mask, wherein: the phase shift mask includes on a transmissive substrate: main patterns arranged at a first pitch, each of the main patterns having a first area, assist patterns surrounding the main patterns and arranged at the first pitch, each of the assist patterns having a second area less than the first area, and dummy patterns surrounding the assist patterns and arranged at the first pitch, each of the dummy patterns having a third area greater than the first area.
