Patent ID: 8013324

Claim:
A semiconductor structure comprising: a semiconductor nanowire having a constant-width portion located between a first end portion and a second end portion, wherein said constant-width portion has a constant first initial width between said first end portion and said second end portion; a first semiconductor pad located on a substrate and adjoining said first end portion of said semiconductor nanowire, wherein said first end portion has a second initial width that is greater than said first initial width at an interface with said first semiconductor pad; a second semiconductor pad located on said substrate and adjoining said second end portion of said semiconductor nanowire, wherein said second end portion has a first width that is greater than said second initial width at an interface with said second semiconductor pad; a channel region located in said constant-width portion of said semiconductor nanowire and having a doping of a first conductivity type; a gate dielectric located on and surrounding said channel region; and a gate electrode located on and surrounding said gate dielectric.
