The invention relates to a contact feature of a semiconductor device and a method of forming the same. A method includes forming a dielectric layer over an epitaxial source/drain region, forming an opening in the dielectric layer. The opening exposes a portion of the epitaxial source/drain region. A barrier layer is formed on sidewalls and a bottom of the opening. An oxidation process is performed on sidewalls and a bottom of the opening. An oxidation process converts a portion of the barrier layer into an oxidation barrier layer and a portion of the dielectric layer adjacent the oxidation barrier layer into a liner layer. And removing the oxidation barrier layer. The opening is filled with a conductive material from bottom to top, the conductive material being in physical contact with the liner layer.

An opening is formed in the dielectric layer. The opening exposes a portion of the source/drain region. A conductive liner is formed on sidewalls and a bottom of the opening. A surface modification process is performed on the exposed surface of the conductive liner. A surface modification process forms a surface coating over the conductive liner. The surface coating is removed to expose the conductive liner. The conductive liner is removed from sidewalls of the opening. The opening is filled with a conductive material in a bottom-up manner. The conductive material is in physical contact with the remaining portion of the conductive liner and the dielectric layer.
