Abstract
The present technology relates to a light receiving device, a method for manufacturing the same, and a distance measuring device capable of improving distance measurement accuracy by maintaining the balance of transfer capability between transfer transistors. A light receiving device includes a pixel including: an embedded photodiode having a charge storage layer of a second conductivity type different from a first conductivity type of a photoelectric conversion region in a region in the vicinity of a second surface on the opposite side to a first surface that is a light incident surface of a substrate; at least two transfer transistors that transfer a charge stored in the photodiode; and at least one discharge transistor that discharges a charge stored in the photodiode; in the light receiving device, the charge storage layer of the second conductivity type is placed to be, in a planar view, surrounded by gates and sidewalls of the transfer transistors, or gates and sidewalls of the transfer transistors and the discharge transistors. The present technology can be applied to, for example, a distance measuring module that measures the distance to a subject, or the like.
