摘要: A triple p–n junction Si photodetector using 0.25-μm standard CMOS process at 650- and 850-nm wavelengths is presented and investigated. Triple p–n junctions are formed vertically by n+-implant/p-well (N+/HVPW), p-well/n+-buried layer (HVPW/NBL), and n+-buried layer/p-substrate (NBL/P-sub) junctions to attain a wavelength-dependent response. The responsivity and pulse response were characterised in different bias schemes. Measured photocurrents from HVPW/NBL and NBL/P-sub junctions under reverse biasing and a floating electrode on N+-HVPW showed the smallest FWHM values. The −3 dB bandwidth of 1.9 GHz converted from pulse measurement is the highest result ever reported in 654-nm wavelength using standard CMOS technology. The proposed triple p–n junction Si photodetector with bias schemes shows combined excellent performance in 650- and 850-nm wavelengths. 出版者: The Institution of Engineering and Technology 出版日期: 2016-09-29 出處: Electronics letters, 2016-09, Vol.52 (20), p.1707-1708 資源來源: Wiley Online Library Open Access 版權: The Institution of Engineering and Technology 版權: 2020 The Institution of Engineering and Technology 識別號: ISSN: 0013-5194 識別號: ISSN: 1350-911X 識別號: EISSN: 1350-911X 識別號: DOI: 10.1049/el.2016.2260
