Abstract:
Replacement metal gate structures with improved chamfered workfunction metal and self-aligned contact and methods of manufacture are provided. The method includes forming a replacement metal gate structure in a dielectric material. The replacement metal gate structure is formed with a lower spacer and an upper spacer above the lower spacer. The upper spacer having material is different than material of the lower spacer. The method further includes forming a self-aligned contact adjacent to the replacement metal gate structure by patterning an opening within the dielectric material and filling the opening with contact material. The upper spacer prevents shorting with the contact material.

Claim (Index 1):
A method comprising:\n forming a dummy gate structure comprising a first spacer, a gate dielectric material on the first spacer and a metal material on the gate dielectric material; removing an upper portion of the first spacer to form a space between an interlevel dielectric material and the gate dielectric material; and etching the metal material and the gate dielectric material from within the space to form a recessed portion with exposure of sidewalls of the interlevel dielectric material above the first spacer.
