美国贝尔通信研究公司的科学家经多年研究和试验,最近发表一项晶体材料制作工艺流程技术,用以生产高纯度半导体材料.这项工艺技术在薄片上生成晶体层程序中,放弃了传统的制作方法,代之以先进的浮法片原理,受到世界半导体工业界的广泛瞩目.这项新工艺流程称为汽化漂浮取向附生.贝尔通信研究公司已就此制造出如铟镓砷晶体这类高纯度半导体材料.迄今世界上还没有第二家公司或实验室能提取出纯度如此高的材 After many years of research and experimentation, scientists at Bell Communications Research Inc. of the United States recently published a process technology for the fabrication of crystalline materials for the production of high purity semiconductor materials that abandoned the traditional fabrication of thin layers of crystals Method, replaced by advanced float principle, by the world’s semiconductor industry, the widespread attention of this new process known as vaporization floating orientation epiphytic Bell communications research company has made such as indium gallium arsenide crystal such high Purity of semiconductor materials. So far there is no second company or laboratory can extract such a high purity material
