Abstract:
Methods of selectively nitriding surfaces of semiconductor devices are disclosed. For example, a hardmask is formed on the top portion of the fins to create SOI structure. The hardmask may be formed by nitriding the top portion of the fin. In other embodiments, silicon nitride is grown on the top portion of the fin to form the hard masks. In another example, internal spacers are formed between adjacent nanowires in a gate-all-around structure. The internal spacers may be formed by nitriding the remaining interlayer material between the channel region and source and drain regions.

Claim (Index 4):
A semiconductor device, comprising:\n a semiconductor substrate; and at least one semiconductor fin disposed above the semiconductor substrate, the fin comprising:\n a first active channel region on a top portion of the fin; \n a first oxidized region on a first sub-channel portion of the fin, the first sub-channel portion isolates the top portion of the fin from a rest of the semiconductor device; and \n a second active channel region below the first sub-channel portion of the fin,\n the first and second active channel regions of the fin are thinner than the first sub-channel portion of the fin.
