Abstract

According to one embodiment of the invention, a method for providing improved layer adhesion in a semiconductor is provided. The method includes forming a dielectric layer. The method also includes forming a layer of metal in direct contact with the dielectric layer. The method also includes directly exposing the layer of metal, after forming the layer of metal, to plasma at a power level sufficient to penetrate through the layer of metal and reach the dielectric layer.
