    Abstract: Integrated circuit structures having front side signal lines and backside power delivery are described. In an example, an integrated circuit structure includes a plurality of gate lines extending over a plurality of semiconductor nanowire stack or fin channel structures within a cell boundary. A plurality of trench contacts is extending over a plurality of source or drain structures within the cell boundary, individual ones of the plurality of trench contacts alternating with individual ones of the plurality of gate lines. A first signal line, a second signal line, a third signal line, and a fourth signal line are over the plurality of gate lines and the plurality of trench contacts within the cell boundary. A backside power delivery line is coupled to one of the plurality of trench contacts within the cell boundary.

    Abstract: Integrated circuit structures having backside gate tie-down are described. In an example, a structure includes a first vertical stack of horizontal nanowires over a first sub-fin, and a second vertical stack of horizontal nanowires over a second sub-fin, the second vertical stack of horizontal nanowires spaced apart from and parallel with the first vertical stack of horizontal nanowires. A gate structure includes a first gate structure portion over the first vertical stack of horizontal nanowires, wherein the first gate structure extends along an entirety of the first sub-fin. A second gate structure portion is over the second vertical stack of horizontal nanowires, wherein the second gate structure does not extend along an entirety of the second sub-fin. A gate cut is between the first gate structure portion and the second gate structure portion.
