Abstract
The present disclosure relates to a method of performing a semiconductor fabrication process. The method may be performed by forming a spacer material having vertically extending segments along sidewalls of a masking layer and a horizontally extending segment connecting the vertically extending segments. A cut material is formed over a part of the horizontally extending segment, and the horizontally extending segment of the spacer material not covered by the cut material is removed. A layer under the masking layer is patterned according to the masking layer and the spacer material.
