Abstract
A light receiving apparatus includes a light receiving device including a compound semiconductor substrate, photodiodes, and bump electrodes; and a semiconductor integrated device including a silicon substrate and read-out circuits. Bonded, the integrated device and the light receiving device face each other in a direction of a first axis through the bump electrodes. The light receiving device has a back surface with first and second back edges extending in a direction of a second axis intersecting with the first axis. The light receiving device has a first slope face extending from the first back edge along a first reference plane, and a second slope face extending from the second back edge along a second reference plane. The back surface of the light receiving device extends along a third reference plane intersecting with the first axis. The first and second reference planes are inclined with respect to the third reference plane.
