Abstract
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 (1 0 0)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.
