SEMICONDUCTOR PHOTODETECTOR AND RADIATION DETECTING APPARATUS |
摘要 |
A photodiode array PD1 comprises an n-type semiconductor substrate one face of which is an incident surface of light to be detected; a plurality of pn junction-type photosensitive regions 3 as photodiodes formed on the side of a detecting surface that is opposite to the incident surface of the semiconductor substrate; and a carrier capturing portion 12 formed between adjacent photosensitive regions 3 from among the plurality of photosensitive regions 3 on the detecting surface side of the semiconductor substrate. The carrier capturing portion 12 has one or plurality of carrier capturing regions 13 respectively including pn-junctions, arranged at intervals. Thereby can be realized a semiconductor photodetector and a radiation detecting apparatus which can favorably restrain crosstalk from occurring. |
