Conductive via formation utilizing electroplating

A method for forming a conductive via is discussed and includes forming a seed layer over a first side of a semiconductor substrate, wherein the semiconductor substrate includes a first side opposite a second side, forming a via hole in a semiconductor substrate from the second side of the semiconductor substrate, wherein the via hole exposes the seed layer; and electroplating a conductive via material in the via hole from the seed layer. In one embodiment, a continuous conductive layer is formed over and electrically coupled to the seed layer. The continuous conductive layer can serve as the current source while electroplating the conductive via material.
