摘要
用两种方法测量了几种金属薄膜的密度.介绍了应用卢瑟福背散射(RBS)技术结合台阶仪测厚来测量薄膜密度的测量方法,并将所得结果进行了讨论。
The densities of several metal films,such as Au,Ag,Cu,Pd and Co have been determined using two kinds of measurement methods.One is using a Dekdeck2A step instrument in conjunction with a microbalance,and the other is using the step instrument in conjunction with RBS(Rutherford Backscattering Spectrometry)analysis,to measure the density of the films.Comparing the results obtained by these methods,it is found that the first method is simple to understand and easy to operate,but it may produce some error caused by the nonuniformity of the film thickness;The second method can overcome this problem and get reliable results,but it is difficult to get the available RBS spectrum in case of the films are too thick or the elements in the substrate are heavier than those in the films.
