Patent ID: 8900935

Claim:
A method comprising: providing a semiconductor device comprising a substrate, a nanowire, a first structure and a second structure, where the nanowire is suspended between the first structure and the second structure, where the first structure and the second structure overlie the substrate; and performing atomic layer deposition to deposit a film on at least a portion of the semiconductor device, where performing atomic layer deposition to deposit the film comprises performing atomic layer deposition to deposit the film on at least a surface of the nanowire; where the first structure, the second structure and the nanowire comprise parts of a first semiconductor device, where the layer comprises a first layer, where the nanowire comprises a first nanowire, the method further comprising: providing on the substrate a second semiconductor device comprised of a second nanowire, a third structure and a fourth structure, where the second nanowire is suspended between the third structure and the fourth structure; masking the second semiconductor device when performing the atomic layer deposition to deposit the first film at least on a surface of the first nanowire, where the first film is doped with a first dopant; masking the first semiconductor device when performing a second atomic layer deposition to deposit a second film at least on a surface of the second nanowire, where the second film is doped with a second dopant that is different from the first dopant; performing at least one heat treatment on the first semiconductor device and the second semiconductor device to form a first layer, from the first film, on the first nanowire and to form a second layer, from the second film, on the second nanowire; and removing any unreacted portions of the first film and the second film.
