Abstract:
An infrared light-receiving device includes an optical absorption layer disposed on a principal surface of a substrate and an optical filter disposed on the optical absorption layer, the optical filter including first, second, and third semiconductor regions that are arranged in that order in a direction from the optical absorption layer to the optical filter, each of the first, second, and third semiconductor regions including an n-type InGaAs layer. The optical absorption layer includes a type-II superlattice structure. The first semiconductor region contains an n-type impurity with a concentration of 2.0×10 19  cm −3  or more. The third semiconductor region contains an n-type impurity with a concentration of 3.0×10 18  cm −3  or less and 8.0×10 17  cm −3  or more. The second semiconductor region contains an n-type impurity with a concentration between the impurity concentration of the first semiconductor region and the impurity concentration of the second semiconductor region.

Claim (Index 6):
The infrared light-receiving device according to  claim 5 , wherein the second conductivity type semiconductor layer includes a p-type layer made of InP that is in contact with the optical filter so as to form a p-n junction at a boundary between the second conductivity type semiconductor layer and the optical filter.
