A simulation method of resonance reaction yield curve is reported. The boron depth profiles in boron doped amorphous silicon- carbon films prepared in a rf glow discharge at various substrate temperatures were studied by using 11B(p
a )8Be at Ep = 163keV resonance reaction and simulating the reaction yield curve. Some of the characteristics of boron depth profile in these films were presented. The results show that the simulation of resonance reaction yield curve should be effective for improving the depth resolution and simplifying the analysis method of boron depth profiling and useful for the research of boron doped amorphous films.
