Abstract

In this research, the PN junction type Si photodiodes have been fabricated on the low doped P type(Na=7x10**14 cm**-3) and N type (Nd=4x10**14cm**-3) (100) silicon substrates. We could find out that the dark current was lower in the N type substrate than in the P type substrate. Some well designed photodiodes showed relatively good optical and electronic characteristics that the dark current is lower than 5 nA at 10V of reverse bias condition, that the breakdown voltage is higher than 250V, and that the quantum efficiency is larger than 86% at the wavelength of $6328{\AA}$
