產品概述/Product Introduction：

? 氣相外延是一種單晶薄層生長方法

Vapor phase epitaxy is a single crystal thin layer growth method

? 氣相外延廣義上是化學氣相沉積的一種特殊方式，其生長薄層的晶體結構是單晶襯底的延續，而且與襯底的晶向保持對應的關系

Vapor phase epitaxy is a special method of chemical vapor deposition in a broad sense, in which the crystal structure of the thin layer is a continuation of the single crystal substrate and keeps correspond-ing relationship with the crystal orientation of the substrate

? 在半導體科學技術的發展中，氣相外延發揮了重要作用

In the development of semiconductor science and technology, gas phase epitaxy has played an import-ant role
