Abstract

According to one embodiment, a method for patterning a set of features for a semiconductor device includes providing a mask including a substrate and at least one pair of first and second main features disposed on a substrate. The method also includes positioning the mask over a layer of light-sensitive material, and exposing the mask to a light source. The mask also includes at least one sub-resolution feature connecting the first and second main features.
