Her innovative methods have the potential to enhance the efficiency and quality of silicon wafer production.
Latest Patents
Aya Ushioda holds a patent for a "Method for heat-treating silicon wafer." This method is designed to operate in an inert gas atmosphere, allowing for the efficient discharge of SiO gas produced during the melting of a natural oxide film on the silicon wafer's surface. The process effectively suppresses the accumulation of reaction products in the heat treatment chamber, thereby preventing slip deterioration. The wafer is held for a period of 5 to 30 seconds, with a rotational speed set between 80 to 120 rpm. Additionally, the inert gas supply in the chamber is controlled to ensure a gas replacement rate of 90% or more within a temperature range of 900 to 1100° C.
