Abstract

A first photoresist material is formed. The first photoresist material is exposed through a phase shift mask. The first photoresist material is developed to form a first photoresist layer, wherein the first photoresist layer comprises a plurality of first photoresist patterns and a plurality of first openings between the plurality of first photoresist patterns. A first conductive material is formed in the plurality of first openings. A second photoresist layer is formed over the first conductive material, wherein the second photoresist layer comprises at least one second opening. A second conductive material is formed in the at least one second opening. The first photoresist layer and the second photoresist layer are removed, to form a plurality of first conductive patterns and at least one second conductive pattern. A dielectric layer is formed, wherein the at least one second conductive pattern is disposed in the dielectric layer.
