Abstract:
A method and structure for forming a via-first metal gate contact includes depositing a first dielectric layer over a substrate having a gate structure with a metal gate layer. An opening is formed within the first dielectric layer to expose a portion of the substrate, and a first metal layer is deposited within the opening. A second dielectric layer is deposited over the first dielectric layer and over the first metal layer. The first and second dielectric layers are etched to form a gate via opening. The gate via opening exposes the metal gate layer. A portion of the second dielectric layer is removed to form a contact opening that exposes the first metal layer. The gate via and contact openings merge to form a composite opening. A second metal layer is deposited within the composite opening, thus connecting the metal gate layer to the first metal layer.

Claim (Index 15):
The method of  claim 11 , further comprising:\n prior to forming the first metal layer, depositing a second dielectric layer over the substrate; forming an opening within the second dielectric layer to expose the region of the substrate below the first metal layer; and forming the first metal layer within the opening.
