Claim:
1. A method for forming a semiconductor device, the method comprising: forming an amorphous or polycrystalline semiconductor layer adjacently to at least one semiconductor doping region having a first conductivity type located in a semiconductor substrate; incorporating dopants into the amorphous or polycrystalline semiconductor layer during or after forming the amorphous or polycrystalline semiconductor layer; and annealing the amorphous or polycrystalline semiconductor layer to transform at least a part of the amorphous or polycrystalline semiconductor layer into a substantially monocrystalline semiconductor layer and to form at least one doping region having the second conductivity type in the monocrystalline semiconductor layer, such that a p-n junction is formed between the at least one semiconductor doping region having the first conductivity type and the at least one doping region having the second conductivity type.
