Meet us at this virtual event which welcomes all researchers, practitioners and educators interested in SPADs, SPAD imagers, and associated applications.
Meet ams virtually at the ISSW 2020
This virtual workshop focuses on the study, modelling, design, fabrication, and characterization of SPAD sensors. It addresses researchers, practitioners and educators interested in SPADs, SPAD imagers, and associated applications.
ams Speaking Slot on Monday, June 8th
Session "Technology": 13:30-14:10 BST
Presentation title: 3D-Stacked SPAD in 40/45nm BSI Technology
Abstract: We present a Single Photon Avalanche Diode (SPAD) fabricated in a 3D stacked backside illumination (BSI) technology. Several SPAD layouts with a pitch of ~12.5um, but differing by the fill factor in the range of 25% to 57% are compared with respect to key performance parameters like breakdown voltage(VBD), dark count rate (DCR), photon detection efficiency (PDE), timing jitter, cross-talk and after pulsing probability. The best performing SPAD with a breakdown voltage of 17V achieves a DCR of 15cps and a PDE of 4.8% at 940nn when operated with an excess bias of 2.0V.
