Abstract:
Semiconductor device and the manufacturing method thereof are disclosed herein. An exemplary semiconductor device comprises a substrate; a gate structure disposed over the substrate and over a channel region of the semiconductor device, wherein the gate structure includes a gate stack and spacers disposed along sidewalls of the gate stack, the gate stack including a gate dielectric layer and a gate electrode; a first metal layer disposed over the gate stack, wherein the first metal layer laterally contacts the spacers over the gate dielectric layer and the gate electrode; and a gate via disposed over the first metal layer.
