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 11):
The method of  claim 10  further comprising, after the photo resist is removed, etching an etch stop layer underlying the dielectric layer to reveal a conductive feature underlying the etch stop layer.
