摘要： Common-substrate semiconductor devices having nanowires or semiconductor bodies with differing material orientation or composition and methods to form such common-substrate devices are described. For example, a semiconductor structure includes a first semiconductor device having a first nanowire or semiconductor body disposed above a crystalline substrate. The first nanowire or semiconductor body is composed of a semiconductor material having a first global crystal orientation. The semiconductor structure also includes a second semiconductor device having a second nanowire or semiconductor body disposed above the crystalline substrate. The second nanowire or semiconductor body is composed of a semiconductor material having a second global crystal orientation different from the first global orientation. The second nanowire or semiconductor body is isolated from the crystalline substrate by an isolation pedestal disposed between the second nanowire or semiconductor body and the crystalline substrate.

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： A complementary metal oxide semiconductor integrated circuit may be formed with a PMOS device formed using a replacement metal gate and a raised source drain. The raised source drain may be formed of epitaxially deposited silicon germanium material that is doped p-type. The replacement metal gate process results in a metal gate electrode and may involve the removal of a nitride etch stop layer.

摘要： Semiconductor devices having metallic source and drain regions are described. For example, a semiconductor device includes a gate electrode stack disposed above a semiconducting channel region of a substrate. Metallic source and drain regions are disposed above the substrate, on either side of the semiconducting channel region. Each of the metallic source and drain regions has a profile. A first semiconducting out-diffusion region is disposed in the substrate, between the semiconducting channel region and the metallic source region, and conformal with the profile of the metallic source region. A second semiconducting out-diffusion region is disposed in the substrate, between the semiconducting channel region and the metallic drain region, and conformal with the profile of the metallic drain region.
