ABSTRACT:
A silicon ribbon growth wheel having an internal cooling fluid contacting surface modified to provide a lateral temperature profile on the wheel surface of lower temperature near the wheel edges. In a preferred form the inner surface is provided with grooves near the wheel edges to increase heat conduction to the cooling fluid at the wheel edges. A method for surface temperature profiling the growth wheel is also disclosed. A method for surface temperature profiling the growth wheel is also disclosed.
