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 13):
A gate structure, comprising:\n a first work function metal layer disposed over a gate dielectric layer and lining a portion of a sidewall of a spacer; a second work function metal layer disposed over the first work function metal layer; a third work function metal layer disposed over the second work function metal layer; and a filling metal in contact with the first work function metal layer and the third work function metal layer, wherein the second work function metal layer is spaced apart from the filling metal by the third work function metal layer.
