Abstract (in Japanese) (See Japanese page) 
(in English) To realize a high-sensitivity CMOS image sensor using avalanche multiplication, we investigate the feasibility of a pixel structure that uses a crystalline selenium-based photoelectric conversion element and a crystalline oxide semiconductor (OS)-based FET. The OS FET is shown to have a withstand voltage of over 20 V, with which the photoelectric conversion element can cause avalanche multiplication. An amorphous selenium-based photoelectric conversion element in which holes are mainly travelling carriers and which is formed on a pixel electrode on a pseudo OS FET/CMOS FET substrate exhibits favorable photoconductivity, indicating compatibility with an OS FET/CMOS FET hybrid process. This shows the potential for realizing an OS/CMOS image sensor using avalanche multiplication in a crystalline selenium-based photoelectric conversion element.
