Light receiving device and distance measuring device

Disclosed is a light receiving element including an on-chip lens, a wiring layer, and a semiconductor layer disposed between the on-chip lens and the wiring layer. The semiconductor layer includes a photodiode, a first transfer transistor that transfers electric charge generated in the photodiode to a first charge storage portion, a second transfer transistor that transfers electric charge generated in the photodiode to a second charge storage portion, and an interpixel separation portion that separates the semiconductor layers of adjacent pixels from each other, for at least part of the semiconductor layer in the depth direction. The wiring layer has at least one layer including a light blocking member. The light blocking member is disposed to overlap with the photodiode in a plan view.

Light receiving element, ranging module, and electronic apparatus

The present technology relates to a light receiving element and a ranging module that can improve characteristics. A light receiving element includes: light receiving regions each including a first voltage application unit to which a first voltage is applied, a first charge detection unit provided around the first voltage application unit, a second voltage application unit to which a second voltage different from the first voltage is applied, and a second charge detection unit provided around the second voltage application unit; and an isolation portion that is arranged at a boundary between the light receiving regions adjacent to each other, and isolates the light receiving regions from each other. The present technology can be applied to a light receiving element.

The present disclosure relates to an imaging device, an imaging apparatus, and an electronic device capable of light-shielding a charge accumulation unit at low cost, while maintaining a charge transfer path from a photodiode to a charge accumulation unit. A depth of a trench that forms a trench buried film having a light-shielding characteristic for preventing color mixture of the photodiodes is adjusted according to a contact amount of a reactive gas by adjusting, among the shapes of a photomask pattern, a width of the trench through which the reactive gas flows or the number of intersections of the trenches at a portion in which the trench buried film is formed. As a result, the trench buried films having a plurality of depths can be formed by a single dry etching with one mask pattern, and the manufacturing cost is reduced. Application to an imaging device is possible.
