Abstract:
Contact structures and methods of forming contacts structures are contemplated by this disclosure. A structure includes a dielectric layer over a substrate, an adhesion layer, a silicide, a barrier layer, and a conductive material. The dielectric layer has an opening to a surface of the substrate. The adhesion layer is along sidewalls of the opening. The silicide is on the surface of the substrate. The barrier layer is on the adhesion layer and the silicide, and the barrier layer directly adjoins the silicide. The conductive material is on the barrier layer in the opening.

Claim (Index 1):
A structure comprising:\n a dielectric layer over a top surface of a semiconductor region, the dielectric layer having an opening exposing the top surface of the semiconductor region; an adhesion layer along sidewalls of the opening, wherein the adhesion layer comprises a metal; a silicide region over and contacting the top surface of the semiconductor region; a barrier layer comprising:\n a first portion directly over and physically contacting the silicide region, wherein the first portion has a first thickness; and \n a second portion adjacent sidewalls of the opening, wherein the second portion has a second thickness smaller than the first thickness, wherein an entirety of the silicide region comprises a same metal as in the adhesion layer; and \n a conductive material over the barrier layer and in the opening.
