Abstract: An open loop control method for use with an apparatus for growing a silicon single crystal having a zero dislocation state and an improved diameter and growth rate uniformity in accordance with the Czochralski process. According to the invention, a heat and mass transfer model based on the silicon charged to a crucible is determined as a function of one or more reference parameters. The reference parameter values are determined from the growth of a reference silicon single crystal. A power profile is then determined as a function of the heat and mass transfer model for a given pull rate profile and model diameter profile. The power profile generated is representative of the power supplied to a heater for providing an amount of thermal energy to the crucible for substantially maintaining a thermal equilibrium at the interface between the melt and the crystal.
