    摘要: A method of forming a semiconductor device is disclosed. The method including providing a substrate with at least one insulating layer disposed thereon, the at least one insulating layer including a trench; forming at least one liner layer on the at least one insulating layer; forming a nucleation layer on the at least one liner layer; forming a first metal film on a surface of the nucleation layer; etching the first metal film; and depositing a second metal film on the etched surface of the first metal film, the second metal film substantially forming an overburden above the trench.
