Latest Patents

One of his latest patents is titled "Method and system for measuring polycrystalline chunk size and distribution in the charge of a Czochralski process." This invention provides a method and system for determining the size of polycrystalline silicon chunks used in the Czochralski silicon growing process. The process involves arranging the chunks on a measuring background, capturing their images with a camera, and using an image processor to analyze the dimensions of the chunks. A size parameter associated with the chunks is then determined.

Another notable patent is "Process and apparatus for preparation of silicon crystals with reduced metal content." This invention discloses a method and apparatus for producing silicon single crystals with reduced contamination. In one embodiment, the structural components made of graphite in the hot zone of the crystal pulling apparatus are protected by two layers. The first layer is applied directly to the graphite, while the second layer, made of silicon, covers the first layer. In another embodiment, a single protective layer made of a mixture of silicon carbide and silicon is applied directly to the graphite.
