Paper Abstract

In this work, by optimizing the structure and thickness of the on-chip multilayer dielectric stack using SiO2 and low extinction coefficient Si3N4 with the high UV-light sensitivity photodiode technology, high external Q.E. and high stability to UV-light were both successfully obtained. By changing the structure of on-chip multilayer dielectric stack and film thickness, we obtained the photodiode with the high external Q.E. in the desired UV-light region.
