Abstract:
A gate structure includes at least one spacer defining a gate region over a semiconductor substrate, a gate dielectric layer disposed on the gate region over the semiconductor substrate, a first work function metal layer disposed over the gate dielectric layer and lining a bottom surface of an inner sidewall of the spacer, and a filling metal partially wrapped by the first work function metal layer. The filling metal includes a first portion and a second portion, wherein the first portion is between the second portion and the semiconductor substrate, and the second portion is wider than the first portion.

Claim (Index 17):
A method of forming a gate structure, the method comprising:\n forming a first work function metal layer on a sidewall of a material that defines a recess; forming a second work function metal layer over the first work function metal layer; removing a first portion of the second work function metal layer to expose a first portion of a sidewall of the first work function metal layer, wherein a second portion of the second work function metal layer remains on a second portion of the sidewall of the first work function metal layer after the removing; filling the recess with a filling metal; removing a portion of the filling metal to expose the first work function metal layer and form a second recess; and depositing a protection layer in the second recess to contact the first work function metal layer, wherein the protection layer is spaced apart from the second portion of the second work function metal layer by the filling metal.
