    Abstract: A dielectric structure is formed over a layer than contains a conductive component. An opening is formed in the dielectric structure. The opening exposes an upper surface of the conductive component. A first deposition process is performed that deposits a first conductive layer over the dielectric structure and partially in the opening. A treatment process is performed on a first portion of the first conductive layer formed over the dielectric structure. The treatment process introduces a non-metal material to the first portion of the first conductive layer. After the treatment process has been performed, a second deposition process is performed that at least partially fills the opening with a second conductive layer without trapping a gap therein.
