半导体色敏器件,是一种新型的半导体光敏器件.它是由同一硅基片上两个深浅不同的PN结构成.深结结深为12μm左右,浅结结深0.5μm左右.利用这两个深浅不同的PN结,对波长不同的光的短路电流响应不同,来检测入射光的波长.这种器件可以方便、快速地检测波长在5000～11000A范围内光波的波长.而且还可用于一些颜色、染料的色检查,印刷物的色判别,彩色电视彩条和彩色电影拷贝的色调等与颜色有关的各个领域.本文主要介绍硅色敏器件的基本原理、试制结果及其理论分析. Semiconductor color-sensitive device, is a new type of semiconductor photo-sensing device, which is composed of two different PN structures on the same silicon substrate, deep junction depth of about 12μm, shallow junction depth of about 0.5μm. Different PN junctions with different shades respond to the short-circuit current of different wavelengths of light to detect the incident light wavelength. This device can easily and quickly detect wavelengths of light in the wavelength range of 5000 to 11000 A. It can also be used in some colors , Dye color inspection, printed matter color discrimination, color TV color bars and color film copy color and other areas related to color.This paper introduces the basic principles of silicon color devices, trial results and theoretical analysis.
