发明名称 COPPER ETCHING INTEGRATION SCHEME
摘要 The present disclosure is directed to an interconnect structure. The metal interconnect structure has a metal body disposed over a semiconductor substrate and a projection extending from the metal body. A barrier layer continuously extends over the projection from a first sidewall of metal body to an opposing second sidewall of the metal body. A layer of dielectric material is disposed over the semiconductor substrate at a position abutting the metal body and the projection.

主权项 1. An interconnect structure, comprising: a metal body disposed over a semiconductor substrate; a projection extending outward from a top surface of the metal body; a barrier layer continuously extending over the projection from a first sidewall of the metal body to an opposing, second sidewall of the metal body; and a layer of dielectric material disposed over the semiconductor substrate at a position abutting the metal body and the projection.
