Patent ID: 8211741

Claim:
A method of forming a semiconductor structure comprising: forming a semiconducting carbon nanotube on a substrate, forming and patterning a first charge-carrier-inducing material layer on said semiconducting carbon nanotube, wherein said first charge-carrier-inducing material layer induces charges of a first conductivity type in at least one underlying region of said semiconducting carbon nanotube; forming and patterning a second charge-carrier-inducing material layer on said semiconducting carbon nanotube, wherein said second charge-carrier-inducing material layer induces charges of a second conductivity type in at least another underlying region of said semiconducting carbon nanotube, wherein said second conductivity type is the opposite of said first conductivity type; and forming an electrical isolation structure electrically isolating said at least one underlying region from said at least another underlying region, wherein said forming of said electrical isolation structure comprises removing a portion of said semiconducting carbon nanotube between said at least one underlying region and said at least another underlying region.
