Latest Patents

Kazunori Funazaki holds a patent for a "Method for producing high-purity polycrystalline silicon." This invention provides technology for achieving higher purification levels of polycrystalline silicon. The process begins with the preparation of trichlorosilane as a sample, followed by an analysis of carbon-containing impurities using the GC/MS-SIM method. The quality of the trichlorosilane is determined based on the analysis results. If the trichlorosilane is deemed suitable, it is used as the raw material for producing high-purity polycrystalline silicon through the CVD method. Conversely, if it is determined to be unsuitable, it is not used in the production process. The method also allows for the simultaneous separation of chlorosilanes and hydrocarbons, enhancing the efficiency of the purification process.
