H01L31/1127 - CPC Classification

Classification description:

Semiconductor devices sensitive to infra-red radiation, light, electromagnetic radiation of shorter wavelength or corpuscular radiation and specially adapted either for the conversion of the energy of such radiation into electrical energy or for the control of electrical energy by such radiation; Processes or apparatus specially adapted for the manufacture or treatment thereof or of parts thereof; Details thereof in which radiation controls flow of current through the device, e.g. photoresistors characterised by at least one potential-jump barrier or surface barrier, e.g. phototransistors; Devices sensitive to infra-red, visible or ultra-violet radiation characterised by field-effect operation, e.g. junction field-effect phototransistor Devices with PN heterojunction gate
