    摘要: A method of fabricating a semiconductor device facilitates the forming of a conductive pattern of features having different widths. A conductive layer is formed on a substrate, and a mask layer is formed on the conductive layer. First spaced apart patterns are formed on the mask layer and a second pattern including first and second parallel portion is formed beside the first patterns on the mask layer. First auxiliary masks are formed over ends of the first patterns, respectively, and a second auxiliary mask is formed over the second pattern as spanning the first and second portions of the second pattern. The mask layer is then etched to form first mask patterns below the first patterns and a second mask pattern below the second pattern. The first and second patterns and the first and second auxiliary masks are removed. The conductive layer is then etched using the first and second mask patterns as an etch mask.
