(四)光敏半导体器件和传感器半导体光电子器件是可进行光电转换的半导体器件的统称,按其光学功能,它们通常分为光探测器、光发射器、光耦合器、光显示器以及若干特殊应用的器件等几大类,其中探测器和发光器是核心部件。半导体光电器件国外从六十年代以后得到了突飞猛进的发展,国内的主要生产厂家有北京光电器件厂和苏州半导体总厂,从七十年代开始已经有系列产品供应市场。 1.光电探测器件包括半导体硅光电二极管和硅光电三极管,目前国内定型生产的硅光电二极管有PN结型、PIN型、雪崩型等三种类型。硅光电三
(D) Photosensitive Semiconductor Devices and Sensors Semiconductor optoelectronic devices are collectively referred to as semiconductor devices capable of photoelectric conversion. According to their optical functions, they are usually classified into photodetectors, light emitters, optical couplers, light displays and some special applications Devices and other categories, of which detectors and light emitters are the core components. Semiconductor optoelectronic devices from abroad since the 1960s has been by leaps and bounds, the major domestic manufacturers Beijing Optoelectronic Devices Factory and Suzhou Semiconductor Plant, from the seventies have been a series of products supply market. 1. Photoelectric detection devices include semiconductor silicon photodiodes and silicon phototransistor, the current domestic stereotypes of silicon photodiodes have PN junction type, PIN type, avalanche type and other three types. Silicon photoelectric three
