Abstract:
1. An integrated electronic circuit comprising: a substrate having an active portion of crystalline semiconductor material; a thin fin portion of crystalline semiconductor material having an electrical doping of a first type, and being in contact with the active portion of the substrate at a surface of said substrate, the thin fin portion comprising at least a channel of a transistor with an electrical direction of conduction parallel to the surface of the substrate, and a height perpendicular to said substrate surface; a part of the active portion of the substrate which is in contact with the fin being electrically doped with a second type of doping which is the opposite of said first type, wherein at least one doping boundary of said doped part of the active portion is aligned with a side edge of the thin fin portion in a direction perpendicular to the substrate surface.
