Latest Patents
Among his latest patents, Morita has developed a groundbreaking **Method of Manufacturing Semiconductor Wafer**. This method includes a unique approach to differentiate the glossiness of the front and rear surfaces of the wafer during manufacturing. By utilizing a carrier plate with a wafer holding hole and employing a circular motion without rotation, this technique allows for simultaneous polishing of both surfaces. Notably, the method incorporates various abrasive materials tailored for specific polishing needs.
Additionally, Morita holds a patent for the **Method for Manufacturing SOI Wafer**. This innovative process facilitates the creation of thin silicon-on-insulator (SOI) layers with uniform thickness across the plane. The process starts with the formation of an oxygen ion implanted layer on an active layer wafer, which is then laminated to a base wafer with an embedded oxide film. The remaining portion is carefully polished or etched, resulting in a thin SOI layer ready for use.
