Abstract:

Using the thermodynamic software FACT, and the SINTEF database for high purity silicon, the interaction coefficients between the doping elements boron and phosphorus and a range of impurity elements (Al, C, Ca, Cr, Cu, Fe, Mg, Mn, Mo, N, Na, Ni, O, Sn, Ti, V, Zn, Zr) have been calculated in liquid silicon in the temperature range 1420-1620oC. The calculations predict significant interactions between boron and phosphorus and all the evaluated elements, except between phosphorus and nitrogen, where no significant interaction was found.
