Solid state radiation detector with enhanced life duration

Abstract

A solid state photosensitive detector including a solid state photosensitive sensor associated with a converter designed to convert radiation to be detected into radiation to which the photosensitive sensor is sensitive. The photosensitive sensor includes one or more photosensitive elements connected to conductors and a passivation layer covering the photosensitive elements and the conductors to protect them. Between the passivation layer and the converter, a barrier is provided that is impermeable to at least one chemical species that is corrosive for the sensor, capable of being released by the converter during at least one chemical reaction. Such a detector may find particular application to radiation detectors for medical radiology.
