Class Information
Number: 257/E31.001
Name: Active solid-state devices (e.g., transistors, solid-state diodes) > Semiconductor devices responsive or sensitive to electromagnetic radiation (e.g., infrared radiation, adapted for conversion of radiation into electrical energy or for control of electrical energy by such radiation processes, or apparatus peculiar to manufacture or treatment of such devices, or of parts thereof) (epo)
Description: This main group provides for semiconductor devices that are sensitive to infra-red radiation, light, electromagnetic radiation of shorter wavelength or corpuscular radiation and adapted either for the conversion of the energy of such radiation into electrical energy or for the control of electrical energy by such radiation, and processes or apparatus peculiar to the manufacture or treatment of such devices or of parts thereof. This subclass is substantially the same in scope as ECLA classification H01L31/00.
