  • Method for preparation of a photosensor
    Patent number: 4581099
    Abstract: A method for preparing a photosensor having electrodes formed on a photoconductive layer through an intermediary ohmic contact layer is provided which comprises forming an ohmic contact layer on a photoconductive layer, forming electrodes with a desired shape on the ohmic contact layer, then removing the ohmic contact layer at the exposed portion for photoelectric transducing by the etching method and thereafter applying heat treatment, thereby forming a photosensor array.
