Abstract:
Semiconductor nanowire devices having cavity spacers and methods of fabricating cavity spacers for semiconductor nanowire devices are described. For example, a semiconductor device includes a plurality of vertically stacked nanowires disposed above a substrate, each of the nanowires including a discrete channel region. A common gate electrode stack surrounds each of the discrete channel regions of the plurality of vertically stacked nanowires. A pair of dielectric spacers is on either side of the common gate electrode stack, each of the pair of dielectric spacers including a continuous material disposed along a sidewall of the common gate electrode and surrounding a discrete portion of each of the vertically stacked nanowires. A pair of source and drain regions is on either side of the pair of dielectric spacers.

Claim (Index 21):
The method of  claim 19 , wherein removing portions of the sacrificial layers of the fin structure in the source and drain regions and removing portions of the sacrificial layers of the fin structure in the channel region comprises removing sacrificial silicon germanium using a wet etching process with a composition selected from the group consisting of an aqueous carboxylic acid/nitric acid/HF solution and an aqueous citric acid/nitric acid/HF solution.
