Abstract

Embodiments of the present invention are directed to a method of forming a conductive via. The method includes forming an opening in a substrate and forming a conductive material along sidewall regions of the opening, wherein the conductive material occupies a first portion of an area within the opening. The method further includes forming an insulating fill in a second portion of the area within the opening, wherein at least one surface of the conductive material and at least one surface of the insulating fill are substantially coplanar with a front surface of the substrate.
