摘要

A method for analyzing sub-micron devices by Rutherford backscattering spectrometry is presented. Using simplifying assumptions, we are able to simulate the backscattering spectrum of laterally non-uniform samples. The method has been verified with Ni/Pt laterally non-uniform layers on (100)Si substrate and has been applied to characterize the formation of Ni silicide in structures similar to metal oxide semiconductor (MOS) transistors. It is shown that the analysis of devices with a linewidth as low as 0.25 μm is possible using micro RBS and the method of simulation that we have developed.
