Claim:
1. A method comprising: forming a first metal layer over a substrate; forming an insulator layer over the first metal layer and directly on the substrate such that the insulator layer physically contacts the substrate, wherein the first metal layer is disposed along a first sidewall of the insulator layer; forming a second metal layer along a second sidewall of the insulator layer such that a first surface of the first metal layer is substantially coplanar with a second surface of the second metal layer, wherein the second sidewall of the insulator layer opposes the first sidewall of the insulator layer; etching the first metal layer and the second metal layer to form a fin feature from the insulator layer that protrudes beyond the first metal layer and the second metal layer; and forming a first via and a second via that are each coupled to the first metal layer and the second metal layer respectively.
