Our main results on the study of both single pixels and Silicon Photomultiplier arrays produced by STMicroelectronics in Catania are reviewed. Our data, coupled to an extensive simulation study, show that the single pixel technology is close to its ultimate physical limit. The distribution of dark current in large arrays follows a Poissonian law. Cross talk effects are strongly reduced by the presence of optical trenches surrounding each pixel of the array. Finally, we demonstrate that these devices can also be used as single photon counters also without a complex amplification stage.
