LIGHT RECEPTION DEVICE AND DISTANCE MEASUREMENT MODULE
Publication/Patent Number: US2021135022A1 Publication Date: 2021-05-06 Application Number: 16/633,713 Filing Date: 2019-07-04 Inventor: Murase, Takuro   Watanabe, Ryota   Wakano, Toshifumi   Maruyama, Takuya   Otake, Yusuke   Imoto, Tsutomu   Isogai, Yuji   Assignee: SONY SEMICONDUCTOR SOLUTIONS CORPORATION   IPC: H01L31/02 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.

EP3789730A1
LIGHT-RECEIVING ELEMENT AND DISTANCE MEASUREMENT MODULE
Publication/Patent Number: EP3789730A1 Publication Date: 2021-03-10 Application Number: 19832264.6 Filing Date: 2019-07-04 Inventor: Isogai, Yuji   Imoto, Tsutomu   Maruyama, Takuya   Murase, Takuro   Watanabe, Ryota   Wakano, Toshifumi   Assignee: Sony Semiconductor Solutions Corporation   IPC: G01C3/06 Abstract: The present technology relates to a light reception device and a distance measurement module that make it possible to improve a characteristic. 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 to which a first voltage is applied and a first charge detection portion arranged around the first voltage application portion, and a second tap having a second voltage application portion to which a second voltage different from the first voltage is applied and a second charge detection portion arranged around the second voltage application portion The on-chip lens is configured such that the position thereof differs depending upon an in-plane position of a pixel array section, so that an optical path length or a DC contrast of a chief ray from an object is uniform at in-plane pixels of the pixel array section. 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.
