Abstract
A method of forming a semiconductor device comprises forming a first etch stop layer over a substrate. The method also comprises forming a low-k dielectric layer comprising carbon over the first etch stop layer. The method further comprises forming an opening in the low-k dielectric layer. The method additionally comprises filling the opening with a conductive layer. The method also comprises performing a remote plasma treatment on the low-k dielectric layer and the conductive layer. The method further comprises forming a second etch stop layer over the treated conductive layer and the treated low-k dielectric layer.
