Abstract

Silicon Photomultipliers (SiPMs) are fabricated in two different configurations: P-on-N and N-on-P junctions. More particularly P-on-N SiPMs are more suitable for application in Positron Emission Tomography (PET), due to their higher sensitivity in blue wavelength range where common PET scintillators have their emission spectrum. In this paper we will report on the electro-optical performances of the first P-on-N SiPMs manufactured at STMicroelectronics-Catania. The results obtained on these devices are compared with those measured on the standard N-on-P technology. We will show that the performances of the new devices are extremely promising in terms of higher photon detection efficiency in blue wavelength range and lower cross talk effects.
