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 6):
The replacement gate structure of  claim 1 , further comprising a cap material on the replacement gate material, encapsulating an upper portion of the replacement gate material and in direct contact with sidewalls of the spacer.
