Patent ID: 8263480

Claim:
A method for the site-selective growth of horizontal nanowires, the method comprising the steps of: forming a first silicon oxide film on a silicon substrate (first step); forming at least one pi-shaped aluminum layer having a thickness, a length and a width at sites where it is desired to grow nanowires on the first silicon oxide film by patterning (second step); forming a second silicon oxide thin-film to cover all surfaces except surfaces of one side of the pi-shaped aluminum layer (third step); anodizing the uncovered surfaces of the pi-shaped aluminum layer to a depth to form hollow channels, each of which is surrounded by an aluminum oxide film, in a direction parallel to the silicon substrate (fourth step); depositing catalytic metal layers on bottom surfaces of the hollow channels opposed to openings of the hollow channels (fifth step); and growing nanowires from the catalytic metal layers within the hollow channels in the direction parallel to the silicon substrate (sixth step).
