Abstract
NPN phototransistors have been fabricated on high-purity silicon substrate. The devices have been produced by ITC-IRST in the framework of a National Research Project funded by the Italian Education, University and Research Ministry (MIUR). The phototransistor emitter is composed of a phosphorus n(+) implant, the base is a diffused highenergy boron implant, and the collector is the 300 pin thick silicon bulk. Several devices have been investigated. Results with 22 keV X-ray from a Cd-109-radioactive source and visible light irradiation are presented.
