ABSTRACT:
A silicon ribbon growth wheel having a thermal resistance zone between an outer silicon contacting surface and an inner cooling fluid contacting surface to control rate of heat flow from the outer to inner surfaces. In a preferred form the thermal resistance zone is defined by a row of holes through the wheel near the outer surface with said holes isolated from the cooling fluid. A method for controlling the heat flow is also diclosed.
