Abstract: A two-dimensional axisymmetric and three-dimensional mixed numerical models
were designed for Czochralski silicon single crystal growth in horizontal magnetic field. The
results show that the exact distribution of temperature and velocity can be calculated only
through three-dimensional simulation due to non-axial symmetry of the horizontal magnetic field.
The stream function of melt and the shape of solid-liquid interface also have non-axial symmetry,
and such non-axial symmetry changes with magnetic field intensity. The increase of crystal
rotation velocity is favorable for the decrease of the non-axial symmetry of the solid-liquid
interface shape, changing the unevenness of the interface shape. The increasing crucible rotation
enhances the uniformity of temperature distribution in the melt, however, the radial
temperature gradient of the melt increases.
