摘要： Nanowire structures having wrap-around contacts are described. For example, a nanowire semiconductor device includes a nanowire disposed above a substrate. A channel region is disposed in the nanowire. The channel region has a length and a perimeter orthogonal to the length. A gate electrode stack surrounds the entire perimeter of the channel region. A pair of source and drain regions is disposed in the nanowire, on either side of the channel region. Each of the source and drain regions has a perimeter orthogonal to the length of the channel region. A first contact completely surrounds the perimeter of the source region. A second contact completely surrounds the perimeter of the drain region.

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.

摘要： Uniaxially strained nanowire structures are described. For example, a semiconductor device includes a plurality of vertically stacked uniaxially strained nanowires disposed above a substrate. Each of the uniaxially strained nanowires includes a discrete channel region disposed in the uniaxially strained nanowire. The discrete channel region has a current flow direction along the direction of the uniaxial strain. Source and drain regions are disposed in the nanowire, on either side of the discrete channel region. A gate electrode stack completely surrounds the discrete channel regions.
