Abstract:
A method includes forming a first pattern having a first opening on a semiconductor substrate. The first opening is then filled. A second pattern of a first and second feature, interposed by the filled opening, is formed on the semiconductor substrate. Spacer elements then are formed on sidewalls of the filled opening, the first feature and the second feature. After forming the spacer elements, the material comprising first and second features is removed to form a second opening and a third opening. The filled opening, the second opening and the third opening are used as a masking element to etch a target layer of the substrate.
