Abstract

The present disclosure is directed to a semiconductor structure that includes a semiconductor substrate. A first interconnect layer is disposed over the semiconductor substrate. The first interconnect layer includes a first dielectric material having a conductive body embedded therein. The conductive body includes a first sidewall, a second sidewall, and a bottom surface. A spacer element has a sidewall which contacts the first sidewall of the conductive body and which contacts the bottom surface of the conductive body. A second interconnect layer overlies the first interconnect layer and includes a second dielectric material with at least one via therein. The at least one via is filled with a conductive material which is electrically coupled to the conductive body of the first interconnect layer.
