Latest Patents

Hansen's latest patents include innovative methods for enhancing the zero dislocation yield of single crystals. One of his notable inventions is a method of reinforcing a crucible used for containing molten semiconductor material during the Czochralski process. This method involves a body of vitreous silica that has a bottom wall and a sidewall formation, which defines a cavity for holding the molten semiconductor material. The inner surface of the sidewall formation is treated with a devitrification promoter, which, when heated, forms a layer of substantially devitrified silica. This layer promotes uniform dissolution of the inner surface and minimizes the release of crystalline silica particulates into the molten semiconductor material. Another patent focuses on surface-treated crucibles that improve zero dislocation performance, ensuring better quality in the crystal growing process.
