20150176151 | SYSTEM AND METHOD FOR FORMING A SILICON WAFER - An apparatus for forming a crystalline ribbon from molten silicon having a silicon ribbon support. A heater is provided including a pair of spaced planar electrodes parallel to the surface of the molten silicon for capacitively coupling radio frequency electrical currents into the material causing a ribbon of material to melt along a zone. A conductive electrode in thermal contact with a respective cooler and a dielectric layer between the conductive and semi-conductive electrodes is provided. A controller configured to control the removal of heat from the melted ribbon of material in a direction substantially perpendicular to the surface of the molten silicon to effect crystal growth, and to control the fluid level of the material in the crucible. | 06-25-2015 |
