Latest Patents
One of McCallum's latest patents is for a heat shield assembly designed for use within a crystal puller. This innovative assembly is strategically positioned above the molten source material in a crucible. It features a central opening that surrounds the ingot as it is pulled from the molten material. The design includes an outer reflector and an inner reflector, which work together to inhibit heat conduction, thereby enhancing the efficiency of the crystal pulling process.
Another significant patent by McCallum involves a crystal puller and method for growing monocrystalline silicon ingots using the Czochralski method. This apparatus includes a housing and a crucible that contains molten silicon. The crucible is engineered to have a high transmittance, allowing for optimal growth conditions for the silicon ingot. The process involves charging polycrystalline silicon into the crucible, melting it, and then pulling a seed crystal to form a monocrystalline ingot.
