Description

Abstract. MPPS is a family of multi-pixel, self-quenching type Geiger Avalanche Photodiodes. We have been continuously improving the MPPC performances and getting better test results. We introduce some of resent progresses on the MPPC. ・ Dark current Decreasing ・ Wider Operating voltage ・ Metal Quenching resister to replace Poly-Si resister ・ Improve Time resolution ・ Decrease Optical cross talk by Tench ・ Small pixel with larger Fill factor ・ 4-side Buttable with Silicon Through Via
