摘要:
The near-infrared photodetector semiconductor device comprises a semiconductor layer (1) of a first type of conductivity with a main surface (10), a trench or a plurality of trenches (2) in the semiconductor layer at the main surface, a SiGe alloy layer (3) in the trench or the plurality of trenches, and an electrically conductive filling material of a second type of conductivity in the trench or the plurality of trenches, the second type of conductivity being opposite to the first type of conductivity.
