The reliability and reproducibility of MPPC

Multi-Pixel Photon Counter (MPPC) is solid-state photon counting device consisting of a Geiger-mode APD and quenching resistor at the most basic level. To improve the total fill factor of a MPPC array, we have adopted new technologies such as metal quenching resistors (MQR), through-silicon vias (TSV), stealth dicing (SD), and highly accurate assembly techniques. We have confirmed the reliability of these new technologies. The innovative technologies that make up the new MPPC will expand the realm of potential applications.
