Abstract
A light receiving device comprises a substrate of a first type on a first electrode, a first region of the first type on the substrate, second regions of the first type arrayed on the first region, and third regions of a second type on the second regions. A first isolation portion is between the adjacent second regions and adjacent third regions. A second isolation portion comprising a metal is embedded the first isolation portions. A fourth region of the second type is on the first region and spaced from the second regions in a second direction with a pair of fifth regions thereon. An insulating film is on the fourth region and the pair of fifth regions. A second electrode is on the insulating film between the pair of fifth regions. The second electrode is comprised of the same metal as the second isolation portion.
