Mask for Forming Patterns of Semiconductor Device

Abstract

A mask for forming patterns of a semiconductor device is provided. The mask includes first and second main patterns disposed to be spaced apart from each other about a cross point and extending in first and second directions different from each other, a third main pattern disposed spaced apart from the first and second main patterns while being disposed between the first and second main patterns so as to overlap the cross point, and at least one auxiliary pattern spaced apart from the third main pattern in the periphery of a portion of the third main pattern, which is not adjacent with the first and second main patterns.

Dependencies are inferred from the claim text.
