Abstract: Embodiments of the present disclosure generally relate to a method for forming an electrically conductive feature on a substrate. In one embodiment, the method includes forming a first conductive layer via physical vapor deposition (PVD) in an opening of a substrate. The first conductive layer has a thickness of less than 20 angstroms. The method further includes forming a second conductive layer via PVD on the first conductive layer. The first conductive layer and the second conductive layer are formed at a temperature of less than 50° C. The method further includes annealing at least a portion of the first conductive layer and the second conductive layer.
