ABSTRACT:
An apparatus and method for control of a shape of a solidification interface in a Czochralski crystal pulling process are provided wherein a bottom heater is disposed below the bottom of the crucible, the bottom heater having a plurality of individually controllable heating elements which are selectively controlled to produce a desired radial temperature distribution across the bottom of the crucible, thereby influencing the flow pattern within the melt.
