Claim 12:
13. The semiconductor device structure as claimed in claim 12, further comprising:
a plurality of second channel structures over the substrate;
a second semiconductor fin between the second channel structures and the substrate, wherein the second semiconductor fin and the semiconductor fin are separated from each other;
a second gate stack wrapped around each of the second channel structures, wherein the second gate stack is wider than the gate stack;
a third epitaxial structure and a fourth epitaxial structure each connecting the second channel structures, wherein each of the third epitaxial structure and the fourth epitaxial structure extends exceeding a bottom surface of the second gate stack; and
a second isolation structure between the second channel structures and the substrate.
