H10F 30/295 Surface barrier or shallow PN junction radiation detectors, e.g. surface barrier alpha-particle detectors
Full Title
Individual radiation-sensitive semiconductor devices in which radiation controls the flow of current through the devices, e.g. photodetectors > the devices having potential barriers, e.g. phototransistors > the devices being sensitive to radiation having very short wavelengths, e.g. X-rays, gamma-rays or corpuscular radiation > Surface barrier or shallow PN junction radiation detectors, e.g. surface barrier alpha-particle detectors
