ABSTRACT:
An improved photo detector is provided by forming a tub of monocrystalline semiconductor material surrounded by a layer of monocrystalline material of opposite conductivity type. The improved structure is manufactured by means of a modified DIC process. The device may by made deep enough to absorb a large portion of the incident radiation near the PN junction without sacrificing a large number of photo-generated carriers to recombination.
