Patent ID: 8299565

Claim:
A semiconductor structure comprising: a first semiconductor structure including a first semiconductor nanowire, a first source-side pad and a first drain-side pad, wherein each of said first source-side pad and said first drain-side pad adjoins said first semiconductor nanowire and comprises a semiconductor material having a doping of a second conductivity type, and wherein a middle portion of said first semiconductor nanowire comprises said semiconductor material and has a doping of a first conductivity type and has a first pair of sidewalls having a first surface orientation and separated by a sublithographic width, wherein said second conductivity type is the opposite of said first conductivity type; and a second semiconductor structure including a second semiconductor nanowire, a second source-side pad and a second drain-side pad, wherein each of said second source-side pad and said second drain-side pad adjoins said second semiconductor nanowire and comprises said semiconductor material having a doping of said first conductivity type, and wherein said second semiconductor nanowire comprises said semiconductor material and has a doping of said second conductivity type and has a second pair of sidewalls having a second surface orientation and separated by another sublithographic width which is between 80% and 125% of said sublithographic width, wherein said second surface orientation is different from said first surface orientation.
