Abstract:
Embodiments of the present invention are directed to formation of fins with different active channel heights in a tri-gate or a Fin-FET device. In an embodiment, at least two fins are formed on a front side of the substrate. A gate structure extends over a top surface and a pair of sidewalls of at least a portion of the fins. In an embodiment, the substrate is thinned to expose the bottom surface of the fins. Next, backside etching may be performed on each fin to form active channel regions. The fins may be recessed to different depths, forming active channel regions with differing heights.

Claim (Index 1):
A semiconductor device, comprising:\n a first fin comprising:\n a first active channel region on a top portion of the first fin; \n a first sub-channel region underneath the first active channel region; and \n a first active channel height from a top surface of the first active channel region to a top surface of the first sub-channel region; and \n a second fin comprising:\n a second active channel region on a top portion of the second fin; \n a second sub-channel region underneath the second active channel region of the second fin; and \n a second active channel height from a top surface of the second active channel region to a top surface of the second sub-channel region, \n wherein the first and second fins have a same height and the first active channel height is substantially different from the second active channel height.
