Patent ID: 8384069

Claim:
A semiconductor structure comprising: a support corresponding to a horizontal plane; at least one block provided on said support, said block comprising: a stack extending along a vertical direction of alternating layers based on a first semiconductor material and layers based on a second semiconductor material different from said first semiconductor material, said layers based on said first semiconductor material presenting greater dimensions than the layers based on said second semiconductor material such that said stack has a lateral tooth profile; a plurality of spacers filling spaces formed by said lateral tooth profile such that said stack presents a substantially flat vertical lateral surface, said spacers being made of a third material different from said first semiconductor material such that a vertical lateral face formed by said substantially flat vertical lateral surface presents alternating lateral bands based on said first semiconductor material and lateral bands based on said third material; said vertical lateral face being partially covered by a material promoting the growth of nanotubes or nanowires exclusively on the lateral bands based on said first semiconductor material or exclusively on the lateral bands based on said third material, said material promoting the growth of nanotubes or nanowires exclusively coating the lateral bands based on said first semiconductor material or exclusively coating the lateral bands based on said third material.
