Abstract

A metal first, via first process for forming interconnects within a metallization layer of a semiconductor device is provided. In an embodiment a conductive material is deposited and the conductive material is patterned into a conductive line and a via. A dielectric material is deposited over the conductive line and the via, and the dielectric material and the via are planarized.
