Claim 7:
8. A semiconductor structure, comprising:
a first fin structure, a second fin structure, and a third fin structure separated from each other;
a plurality of nanosheets separated from the first fin structure, the second fin structure and the third fin structure;
a high-k gate dielectric layer over each of the first fin structure, the second fin structure and third fin structure, and surrounding each of the nanosheets;
a first work function metal layer over the high-k gate dielectric layer and the first fin structure;
a second work function metal layer over the high-k gate dielectric layer and the second fin structure;
a third work function metal layer over the high-k gate dielectric layer and the third fin structure; and
a fourth work function metal layer over the high-k gate dielectric layer and surrounding each of the nanosheets.
