Abstract
A light receiving element array includes a substrate and a laminated semiconductor structure that is formed on the substrate. The laminated semiconductor structure includes a light absorbing layer that is disposed above the substrate and a plurality of window layers of a first conductivity type that are formed apart from each other on the light absorbing layer. Inside the laminated semiconductor structure, there is formed, for each window layer, a first of second conductivity type region that extends into the light absorbing layer from a surface of the window layer at an opposite side to the light absorbing layer. Inside the light absorbing layer, there is formed a second of second conductivity type region that is disposed such as to surround each of the plurality of window layers in plan view and extends from a surface of the light absorbing layer at an opposite side to the substrate toward a surface of the light absorbing layer at the substrate side.
