Patent ID: 8232190

Claim:
A method, comprising: forming a first contact and a second contact in a substrate; forming an insulator layer over and in physical contact with the substrate, the first contact, and the second contact; etching a first via through the insulator layer to expose the first contact; lining sidewalls of the via with a conductive material which makes physical contact with the first contact; forming an insulator material over and in physical contact with the insulator layer and within the via thereby forming the insulator material over and in physical contact with conductive material; etching a second via through the insulator material and the insulator layer to expose the second contact; etching a first trench and a second trench through the insulator material in a same processing step, the first trench being aligned with the first via, and the second being aligned with the second via; and filling the second via, the first trench, and the second trench with a conductive metal in a same processing step, the conductive metal being in physical contact with the second contact, the insulator layer, the conductive material, and the insulator material.
