Abstract

The Multi-Pixel Photon Counter (MPPC) is a solid state photon counting device using Geiger mode APDs with self-quenching resistors. Recent advancements have been low dark current, good breakdown voltage uniformity and higher sensitivity in UV region. A 3×3mm - 4×4ch. monolithic array with silicon through vias has been developed for TOF-PET in order to decrease packaging dead space. We have also studied thin metal film quenching resistors instead of poly-Si to increase QE and decrease the temperature dependency. Finally we are producing an “All in one MPPCs” which includes many of these new technologies.
