Abstract
A method and associated apparatus are disclosed for use in forming crystalline ribbons by pulling a ribbon in a generally horizontal direction from a pool of molten crystal-forming materials, such as silicon or the like. A heat sink is located above the surface of the molten material proximate to the crystal forming area to remove heat therefrom. The heat sink is cooled continuously and heat is transferred from the molten material to the heat sink by a gaseous thermally conductive medium maintained between the heat sink and the surface of the melt.
