Classification: CPC B  H | IPC H

Claim 0:
1. A device comprising:
a first nanostructure;
a second nanostructure over the first nanostructure;
a first gate dielectric material around the first nanostructure;
a second gate dielectric material around the second nanostructure; and
a p-type work function metal extending continuously from the first gate dielectric material to the second gate dielectric material in a region between the first nanostructure and the second nanostructure, wherein the p-type work function metal comprises a seam between the first nanostructure and the second nanostructure, wherein a first portion of the p-type work function metal has a first thickness, wherein the first portion of the p-type work function metal is disposed in the region between the first nanostructure and the second nanostructure, wherein a ratio of the first thickness to a minimum width of the p-type work function metal is in a range of 0.03 to 1, the minimum width of the p-type work function metal being measured in a direction perpendicular to a direction in which the first thickness is measured.
