Abstract
Systems and methods for a semiconductor device having a substrate material with a trench at a front side, a conformal dielectric material over at least a portion of the front side of the substrate material and in the trench, a fill dielectric material on the conformal dielectric material in the trench, and a conductive portion formed during front-end-of-line (FEOL) processing. The conductive portion may include an FEOL interconnect via extending through the fill dielectric material and at least a portion of the conformal dielectric material and having a front side portion defining a front side electrical connection extending beyond the front side of the semiconductor substrate material and a backside portion defining an active contact surface. The conductive portion may extend across at least a portion of the conformal dielectric material and the fill dielectric material and have a backside surface defining an active contact surface.
