Photodiode array and image pickup device using the same |
摘要 |
A photodiode array includes a plurality of photodiodes arranged in a single semiconductor laminate including a first conductivity-type semiconductor layer and an absorption layer overlying the first conductivity-type semiconductor layer. The photodiode array also includes a functional portion among the photodiodes in a predetermined proportion. The functional portion acts as a monitor light receiving portion and/or a charge sweep portion. Each of the photodiodes and functional portion has a second conductivity-type region reaching the absorption layer from the surface of the semiconductor laminate and an electrode in ohmic contact with the second conductivity-type region.
