【Abstract】 With an experimental system composed of an ion gun and a RBS analysis chamber,in situ analysis of low energetic ion sputtering and high energetic ion RBS for thin films is carried out.We analyze,for three kinds of samples,their compositions and deeply\|buried layers.In the analysis of Au/Si sample,the sputtering rate of Au with Ar\++ etching is discussed and in the analysis of deeply\|buried layers of Si/Ge\|Si/Si and WSi\- x /SiO\-2/Si samples,the depth resolution is obviously improved.The advantages and disadvantages of this analytical method in thin film studies,as well as its potential applications,are discussed.更多还原
