摘要
In order to clarify the effects of configuration of magnetic field on the melt-crystal interface shape and the melt convection in a crucible, a set of numerical computations was conducted for a Czochralski furnace for silicon crystals of small diameter by global modeling. Under different combinations of crucible/crystal rotation rates, numerical comparisons were carried out for four configurations of magnetic field: a transverse magnetic field, a vertical magnetic field and two types of cusp-shaped magnetic fields. The computations revealed that each magnetic-field configuration has its own feature in affecting the melt convection and the melt-crystal interface shape when combining with variation in crystal/crucible rotation rates.
