Abstract:
A method for forming a semiconductor device structure is provided. The method includes forming a first mask layer over a dielectric layer. The first mask layer has a trench. The trench has an inner wall and a bottom surface. The method includes forming a second mask layer in the trench. The method includes removing the second mask layer covering the bottom surface to form a second trench in the second mask layer. The second trench exposes the bottom surface and is over a first portion of the dielectric layer. The remaining second mask layer covers the inner wall. The method includes removing the first portion, the first mask layer, and the second mask layer to form a third trench in the dielectric layer. The method includes forming a conductive structure in the third trench.

Claim (Index 15):
A method for forming a semiconductor device structure, comprising:\n forming a first mask layer over a dielectric layer, wherein the first mask layer has a first trench and a second trench, and the first trench has a first inner wall and a first bottom surface; forming a second mask layer over a top surface of the first mask layer and the first inner wall, wherein a thickness of the second mask layer over the first inner wall increases in a direction away from the dielectric layer, the second mask layer has a third trench in the first trench and exposing the first bottom surface, and the third trench and the second trench are respectively over a first portion and a second portion of the dielectric layer; removing the first portion, the second portion, the first mask layer, and the second mask layer to form a fourth trench and a fifth trench in the dielectric layer, wherein the fourth trench is narrower than the fifth trench; and forming a first conductive structure and a second conductive structure respectively in the fourth trench and the fifth trench.
