Utilizing CGSim
a professional crystal growth simulation software developed and designed by STR
combining crystal dynamics and thermodynamics
selecting N-type monocrystalline silicon commonly used dopant phosphorus is selected
according to the polycrystalline silicon mass of 10 times to add phosphorus monomers as dopant
meanwhile selecting eight different crucible rotate speeds of 7-14 r/min and six different crystal rotate speeds of 6-11 r/min are selected
and orthogonal simulation experiments with a higher crystal pulling rate of 1.8 mm/min were conducted to obtain the change of electrical resistivity. By analyzing the parameters of inner crucible melt temperature field and flow field
outer crucible melt temperature field and flow field
solid-liquid interface
defects in the crystal
appropriate crucible rotational speed and crystal rotational speed were obtained. By comparing with the radial resistivity change obtained by converting the phosphorus concentration to the resistivity at the solid-liquid interface
the influencing mechanism of the radial resistivity of the continuous direct-drawing monocrystalline silicon was researched.
