Claim 0:
1. A multi-gate semiconductor device, comprising:
a fin element extending from a substrate;
a plurality of nanowire channel layers including a first nanowire channel layer, disposed over the fin element and a second nanowire channel layer over the first nanowire channel layer;
a first portion of a high-k gate dielectric material extending between the first nanowire channel layer and the second nanowire channel layer and a second portion of the high-k gate dielectric material extending between the first nanowire channel layer and the fin element;
a spacer layer adjacent the first portion of the high-k gate dielectric material and adjacent the second portion of the high-k gate dielectric material; and
a gate electrode disposed over the plurality of nanowire channel layers.
