SOI active pixel detectors of ionizing radiation - Technology and design development

This paper concerns the development of a novel monolithic active pixel radiation sensor based on SOI technology. In this device, the sensitive volume corresponds to a high resistivity SOI "handle" wafer and the front-end CMOS electronics is integrated in the SOI device layer. Pixel test matrices have been manufactured and are under extensive characterization. The conceptual design, together with architecture and technology issues is addressed; the latest experimental results are reported.
