Japan, July 14 -- TOSHIBA CORP has got intellectual property rights for 'PHOTODETECTOR AND DISTANCE MEASURING DEVICE.' Other related details are as follows:
Application Number: JP,2022-140161
Category (FI): H10F30/225,H01L31/10@B,H10F77/14,G01S7/481@Z,G01S7/4863
Stage: PROBLEM TO BE SOLVED: To reduce power consumption.SOLUTION: A photodetector of an embodiment comprises first to seventh semiconductor parts, and a semiconductor layer. The first semiconductor part and the second semiconductor part are of a first conductivity type and provided separate from each other. The semiconductor layer is of the first conductivity type or a second conductivity type and has a first surface and a second surface opposite to each other. The third semiconductor part is of the second conductivity type and provided between the first semiconductor part, second semiconductor part, and the semiconductor layer. The fourth semiconductor part of the first conductivity type and the fifth semiconductor part of the second conductivity type correspond to the first semiconductor part and are provided in contact with each other on a side of the first surface in the semiconductor layer. The sixth semiconductor part of the first conductivity type and the seventh semiconductor part of the second conductivity type correspond to the second semiconductor part and are provided in contact with each other on the side of the first surface in the semiconductor layer. The concentration of impurities in the third semiconductor part is higher than the concentration of impurities in the semiconductor layer.SELECTED DRAWING: Figure 8 (Grant)
