Abstract: A method for forming a semiconductor device includes forming an amorphous semiconductor layer adjacent to a lightly doped region of a semiconductor wafer. The lightly doped region forms at least part of a back side of the semiconductor wafer, and the lightly doped region has a first conductivity type. The method further includes incorporating dopants into the amorphous semiconductor layer during or after forming the amorphous semiconductor layer. The method further includes annealing the amorphous semiconductor layer to transform at least a part of the amorphous semiconductor layer into a substantially monocrystalline semiconductor layer and to form a highly doped region in the monocrystalline semiconductor layer at the back side of the semiconductor wafer. The highly doped region has the first conductivity type.

Abstract: In various embodiments, a gamma ray detector is provided. The gamma ray detector may include a converter element, configured to release an electron when a gamma ray moves at least partially through the converter element. The gamma ray detector may further include a semiconductor detector, arranged to receive the electron and configured to produce a signal when the electron moves at least partially through the semiconductor detector; and an amplifier circuit, coupled to the semiconductor detector and configured to amplify the signal produced by the semiconductor detector. In the gamma ray detector, the converter element may be arranged to at least partially shield the amplifier circuit from electromagnetic radiation.
