Abstract
The present technology relates to a light reception device and a distance measurement module whose characteristic can be improved. The light reception device includes an on-chip lens, a wiring layer, and a semiconductor layer arranged between the on-chip lens and the wiring layer. The semiconductor layer includes a first tap having a first voltage application portion and a first charge detection portion arranged around the first voltage application portion, and a second tap having a second voltage application portion and a second charge detection portion arranged around the second voltage application portion. Furthermore, the light reception device is configured such that a phase difference is detected using signals detected by the first tap and the second tap. The present technology can be applied, for example, to a light reception device that generates distance information, for example, by a ToF method, and so forth.
