Abstract

Abstract A photoelectric conversion device of the type having a photosensor region and a circuit section for processing at least an output signal from the photosensor region, wherein on a first layer formed with an electronic element constituting the circuit section, a second layer with a deposition surface is formed directly or through an interposed insulation layer, and wherein at least one of the electronic element and the photosensor is formed in a crystal layer which has grown from a single nucleus formed on a nucleus forming region on the deposition surface of the second layer, the single nucleus being sufficiently fine for making only a single crystal grow and having a sufficiently high nucleation density than that of the material of the second layer surface.
