Abstract:
Certain embodiments of a semiconductor device and a method of forming a semiconductor device comprise forming a high-k gate dielectric layer over a short channel semiconductor fin. A work function metal layer is formed over the high-k gate dielectric layer. A seamless metal fill layer is conformally formed over the work function metal layer.

Claim (Index 21):
A method of forming a semiconductor device, comprising:\n forming a first dielectric layer over a first semiconductor fin and a second semiconductor fin, the first dielectric layer having a first recess over the first semiconductor fin and a second recess over the second semiconductor fin; forming a high-k dielectric layer in the first recess and the second recess; forming a work function metal layer over the high-k dielectric layer in the first recess and the second recess; forming a titanium aluminum nitride layer over the work function metal layer in the first recess and the second recess, wherein the titanium aluminum nitride layer completely fills remaining portions of the first recess; and forming a metal fill layer over the titanium aluminum nitride layer in the second recess, wherein the metal fill layer completely fills remaining portions of the second recess.
