The present disclosure provides a method including providing a semiconductor substrate and forming a first layer and a second layer on the semiconductor substrate. The first layer is patterned to provide a first element, a second element, and a space interposing the first and second elements. Spacer elements are then formed on the sidewalls on the first and second elements of the first layer. Subsequently, the second layer is etched using the spacer elements and the first and second elements as a masking element.

Method of forming pattern for semiconductor device

A method that includes forming a masking element on a semiconductor substrate and overlying a defined space. A first feature and a second feature are each formed on the semiconductor substrate. The space interposes the first and second features and extends from a first end of the first feature to a first end of the second feature. A third feature is then formed adjacent and substantially parallel the first and second features. The third feature extends at least from the first end of the first feature to the first end of the second feature.
