Epitaxial n-channel JFETs integrated on high resistivity silicon for X-ray detectors

Junction field-effect transistors (JFETs) were fabricated directly onto a high resistivity silicon wafer and tested as readout devices for radiation detectors. The JFETs were fabricated using an n-channel epitaxial process. We report on the design and electrical characteristics of these devices as well as the noise performance and energy resolution obtained with these devices when operated as X-ray spectrometers.<
