Class Information
Number: 257/E31.091
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) > Adapted to control current flow through device (e.g., photoresistor) (epo) > For device having potential or surface barrier (e.g., phototransistor) (epo) > Device sensitive to very short wavelength (e.g., x-ray, gamma-ray, or corpuscular radiation) (epo) > Field-effect type (e.g., mis-type detector) (epo)
Description: This subclass is indented under subclass E31.086. This subclass is substantially the same in scope as ECLA classification H01L31/119.
