硅-二氧化硅界面过渡区的状态与半导体器件制造工艺有密切关系。以不同的光电子发射角对不同的阳极氧化样品得到的XPS(X-ray Photoelectron Spectroscopy)谱表明;阳极氧化生成的氧化层接近双层突变结构
而热氧化生长层的界面存在过渡层。本文讨论了阳极氧化生长过程
分析了两种氧化方法引起过渡区差别的原因.
The status of transition region of Si-SiO2 interface is closely related to the character of device.XPS spectra are obtained from different specimens of anodic oxidation at differnt angles of photo-electron emission. It is shown that the oxide of anodic oxidation has a abrupt structure
and the oxide interface of thermal oxidation has a marked transition layer. The process of the anodic oxidation is discussed and the causes for the different results by the two methods of oxidation are analyzed.
