Abstract:
A method includes forming a dielectric layer, forming a photo resist over the dielectric layer, forming a first mask layer over the photo resist, and forming a second mask layer over the first mask layer. A first-photo-first-etching is performed to form a first via pattern in the second mask layer, wherein the first-photo-first-etching stops on a top surface of the first mask layer. A second-photo-second-etching is performed to form a second via pattern in the second mask layer, wherein the second-photo-second-etching stops on the top surface of the first mask layer. The first mask layer is etched using the second mask layer as an etching mask. The photo resist and the dielectric layer are etched to simultaneously transfer the first via pattern and the second via pattern into the dielectric layer.

Claim (Index 8):
A method comprising:\n forming a dielectric layer; forming a trench in an upper portion of the dielectric layer; applying a photo resist comprising a first portion over the dielectric layer, and a second portion filling the trench; forming a patterned hard mask over the photo resist; etching the photo resist, with a pattern of the patterned hard mask being transferred into the photo resist, wherein the second portion of the photo resist is partially removed to form an opening in the second portion of the photo resist; and extending the opening into a lower portion of the dielectric layer to form a via opening, wherein the lower portion is directly underlying the trench.
