Abstract
A semiconductor light-receiving device includes a substrate having a principal surface including first and second areas; a post disposed on the first area, the post including a semiconductor mesa; and a resin layer disposed on the second area in contact with a side surface of the post. The resin layer has, on a ray extending from a first point within the first area through a second point within the second area, a first thickness and a second thickness respectively at a third point and a fourth point that are located within the second area at different distances from the first point. The distance from the first point to the fourth point is larger than the distance from the first point to the third point. The first thickness is larger than the second thickness. The resin layer has a surface that monotonically changes from the first thickness to the second thickness.
