Abstract
A device includes a first nanostructure; a second nanostructure over the first nanostructure; a first high-k gate dielectric disposed around the first nanostructure; a second high-k gate dielectric being disposed around the second nanostructure; and a gate electrode over the first high-k gate dielectric and the second high-k gate dielectric. A portion of the gate electrode between the first nanostructure and the second nanostructure comprises a first portion of a p-type work function metal filling an area between the first high-k gate dielectric and the second high-k gate dielectric.
