Patent ID: 7935966

Claim:
A semiconductor device comprising, on at least one surface of a crystalline semiconductor substrate: at least one first amorphous semiconductor region doped with a first type of conductivity, which semiconductor substrate comprises, on a same at least one surface; at least one second amorphous semiconductor region doped with a second type of conductivity, opposite the first type of conductivity, wherein the first amorphous semiconductor region, insulated from the second amorphous semiconductor region by at least one dielectric region in contact with the semiconductor substrate also ensuring passivation of the surface of the substrate, and the second amorphous semiconductor region form an interdigitated structure; at least one first metallization area in contact with the first amorphous semiconductor region, at least one second metallization area in contact with the second amorphous semiconductor region; at least one first conductive thermal oxide area located between the first metallization area and the first amorphous semiconductor region; and at least one second conductive thermal oxide area located between the second metallization area and the second amorphous semiconductor region.
