Claim:
1. A light receiving apparatus comprising: a light receiving device including a compound semiconductor substrate having a principal surface, a plurality of photodiodes each having an electrode, and a plurality of bump electrodes each of which is connected to at least one of the electrodes of the photodiodes, the photodiodes being arranged to form an array on the principal surface of the compound semiconductor substrate; and a semiconductor integrated device including a silicon substrate and a plurality of read-out circuits arranged to form an array on the silicon substrate, each of the read-out circuits having an electrode that is electrically connected to the electrode of a corresponding photodiode in the light receiving device through the bump electrodes, wherein the semiconductor integrated device is bonded with the light receiving device so as to face each other in a direction of a first axis through the bump electrodes, the light receiving device has a back surface with a first back edge and a second back edge that extend 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, and the first reference plane and the second reference plane are inclined with the third reference plane.
