藍(lán)寶石系由單晶體絕緣體元素組成，不會(huì)發(fā)生滯后、疲勞和蠕變現(xiàn)象；藍(lán)寶石比硅要堅(jiān)固，硬度更高，不怕形變；藍(lán)寶石有著非常好的彈性和絕緣特性（1000 OC以內(nèi)），因此，利用硅-藍(lán)寶石制造的半導(dǎo)體敏感元件，對(duì)溫度變化不敏感，即使在高溫條件下，也有著很好的工作特性；藍(lán)寶石的抗輻射特性極強(qiáng)；另外，硅-藍(lán)寶石半導(dǎo)體敏感元件，無(wú)p-n漂移，因此，從根本上簡(jiǎn)化了制造工藝，提高了重復(fù)性，確保了高成品率。目標(biāo)物接近傳感器時(shí)，不論目標(biāo)物金屬種類如何。</p><div
