摘要： Complimentary metal-oxide-semiconductor nanowire structures are described. For example, a semiconductor structure includes a first semiconductor device. The first semiconductor device includes a first nanowire disposed above a substrate. The first nanowire has a mid-point a first distance above the substrate and includes a discrete channel region and source and drain regions on either side of the discrete channel region. A first gate electrode stack completely surrounds the discrete channel region of the first nanowire. The semiconductor structure also includes a second semiconductor device. The second semiconductor device includes a second nanowire disposed above the substrate. The second nanowire has a mid-point a second distance above the substrate and includes a discrete channel region and source and drain regions on either side of the discrete channel region. The first distance is different from the second distance. A second gate electrode stack completely surrounds the discrete channel region of the second nanowire.

A gate electrode stack surrounds the plurality of vertically stacked nanowires. A pair of non-discrete source and drain regions is disposed on either side of, and adjoining, the discrete channel regions of the plurality of vertically stacked nanowires.

摘要： Techniques are disclosed for enabling multi-sided condensation of semiconductor fins. The techniques can be employed, for instance, in fabricating fin-based transistors. In one example case, a strain layer is provided on a bulk substrate. The strain layer is associated with a critical thickness that is dependent on a component of the strain layer, and the strain layer has a thickness lower than or equal to the critical thickness. A fin is formed in the substrate and strain layer, such that the fin includes a substrate portion and a strain layer portion. The fin is oxidized to condense the strain layer portion of the fin, so that a concentration of the component in the strain layer changes from a pre-condensation concentration to a higher post-condensation concentration, thereby causing the critical thickness to be exceeded.
