Zusammenfassung:The present disclosure relates to a method of performing a semiconductor fabrication process. The method may be performed by forming a spacer material over an underlying layer. The spacer material has sidewalls defining a first trench. A cut material is formed over the spacer material and within the first trench. The cut material separates the trench into a pair of trench segments having ends separated by the cut material. The underlying layer is patterned according to the spacer material and the cut material.
