Abstract: The present disclosure is directed to a semiconductor structure and a method of manufacturing a semiconductor structure in which a spacer element is formed adjacent to a metal body embedded in a first dielectric layer of a first interconnect layer. A via which is misaligned relative to an edge of the metal body is formed in a second dielectric material in second interconnect layer disposed over the first interconnect layer and filled with a conductive material which is electrically coupled to the metal body. The method allows for formation of an interconnect structure without encountering the various problems presented by via substructure defects in the dielectric material of the first interconnect layer, as well as eliminating conventional gap-fill metallization issues.

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.
