Abstract:The fabrication process of a two-dimensional position sensitive radiation detector (2-D PSD) with a 4 cm 2 active area is presented. Critical steps in the fabrication are emphasised . Edge effects represent critical problems in producing large area ion implanted silicon radiation detectors with low leakage currents and a high breakdown voltage (BV) . Two methods have been used to increase the breakdown voltage of the junction : the use of i) floating held limiting rings (FFLR) and ii) field plates (FP) . Sever… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
