Two types of photodetectors including conventional P+/N-EPI/BN+photodetector and multifinger P+/N-EPI/BN+photodetector were implemented in a standard 0.5μm Biplor,CMOS and DMOS process with different sizes.The performance and parameter of photodetectors were simulated and optimized.Results of the characteristics of photodetectors simulations and tests were presented,which showed that the multi-finger structure P+/N-EPI/BN+photodetector can improve the responsibility at 650nm and decrease the junction capaci...
