The simultaneous diffusion of Au and B was studied at temperatures of between 800 and 1200C by using spreading resistance and Rutherford back-scattering spectrometric methods. Islands of Au formed on the Si surface at high temperatures. In general, B diffusion was enhanced and driven deeper with increasing Au content. The enhancement was attributed to a form of Kirkendall effect.
