Abstract
The present invention provides a semiconductor light receiving element capable of reducing capacity while minimizing increase in travel time of carriers. The semiconductor light receiving element includes a semiconductor stacked structure including a first conductivity type layer, a light absorbing layer, and a second conductivity type layer having a light incidence plane in order. The semiconductor light receiving element has an oxidation layer including a non-oxidation region and an oxidation region in a stacking in-plane direction in the light absorbing layer or between the first conductivity type layer and the light absorbing layer.
