Abstract:
A semiconductor device includes a semiconductor substrate with a first side and a second side, and at least one doping region formed at the first side of the semiconductor substrate. The semiconductor device further includes a first metallization structure at the first side of the semiconductor substrate and on and in contact with the at least one doping region, and a second metallization structure at the second side of the semiconductor substrate. The second metallization structure forms a silicide interface region with the semiconductor substrate and a non-silicide interface region with the semiconductor substrate.

Claim (Index 19):
A method for manufacturing a semiconductor device, the method comprising:\n providing a semiconductor substrate comprising a first side and a second side; forming a first metal layer on and in contact with the second side of the semiconductor substrate; forming a mask on the first metal layer, the mask comprising openings exposing portions of the first metal layer; etching the first metal layer using the mask as an etching mask to remove the exposed portions of the first metal layer from the second side of the semiconductor substrate and to form first metallization regions which remain on the second side of the semiconductor substrate; heating the first metallization regions and the second side of the semiconductor substrate to form silicide interface regions between the first metallization regions and the semiconductor substrate, the second side of the semiconductor substrate being heated to a higher temperature than the first side of the semiconductor substrate; and forming a second metal layer on and in contact with the second side of the semiconductor substrate, the second metal layer completely covering the first metallization regions and forming one or more non-silicide interface regions with the semiconductor substrate.
