Abstract
Various embodiments of the present disclosure are directed towards a method for forming a semiconductor structure. The method includes forming a gate dielectric structure on a substrate. A sidewall spacer is formed around the gate dielectric structure. A metal structure is formed over the gate dielectric structure. A gate body layer is formed over the metal structure. A lower portion of the gate body layer is cupped by the metal structure. A top surface of the gate body layer is vertically offset from a top surface of the metal structure. A conductive via is formed over the metal structure. The conductive via is disposed between outer sidewalls of the gate body layer.
