Abstract:
Self-aligned contacts are provided. In an embodiment the self-aligned contacts are formed by partially removing a first dielectric material from adjacent to a gate electrode and fully removing a second dielectric material from adjacent to the gate electrode. A conductive material is deposited into the regions of the removed first dielectric material and the second dielectric material, and the conductive material and metal gates are recessed below a spacer. A dielectric layer is deposited over the recessed conductive material and the recessed metal gates, and the self-aligned contacts are formed through the dielectric layer.
