Title:
LIGHT RECEIVING ELEMENT AND RANGE FINDING MODULE
Document Type and Number:
WIPO Patent Application WO/2020/017337
Kind Code:
A1
Abstract:
The present technology relates to a light receiving element and a range finding module, which are able to have improved characteristics. A light receiving element according to the present technology is provided with an on-chip lens, a wiring line layer, and a semiconductor layer that is arranged between the on-chip lens and the wiring line layer. The semiconductor layer is provided with: a first tap which comprises a first voltage application part and a first charge detection part that is arranged around the first voltage application part; and a second tap which comprises a second voltage application part and a second charge detection part that is arranged around the second voltage application part. This light receiving element is configured such that a retardation is detected with use of signals that have been detected by the first tap and the second tap. The present technology is applicable, for example, to a light receiving element which produces range information by means of a ToF method, or the like.
