Claim Text:
1. A semiconductor structure, comprising: a plurality of vertically stacked and released nanowires extending through a common metal replacement gate structure; and a plurality of epitaxially grown conductively doped contacts electrically connecting to the stacked nanowires on different sides of the gate structure, in a series configuration; wherein the plurality of conductively doped contacts comprise: a first contact of the doped contacts electrically connecting a first nanowire to a second nanowire on a first side of the gate structure; a second contact of the doped contacts electrically connecting to the first nanowire on a second side of the gate structure; a third contact of the doped contacts electrically connecting the second nanowire to a third nanowire on the second side of the gate structure; a fourth contact of the doped contacts electrically connecting to the third nanowire on the first side of the gate structure; metal contacts electrically connecting the first contact and the second nanowire and the third contact and the third nanowire; and the plurality of vertically stacked nanowires and the doped contacts share the common metal replacement gate structure.
