Abstract:
Temperatures were measured within an industrial Czochralski silicon puller and compared with simulation results. The temperatures were measured by thermocouples in the crystal along the axis as well as inside the lateral and bottom insulations. The temperature distribution of the furnace was computed using three different software codes. It could be demonstrated that today's simulation methods are capable of handling such a complex heat transfer simulation task as that encountered in the case of Czochralski silicon growth furnaces, with the exception of the melt convection problem, which has not yet been satisfactorily solved.
