Latest Patents

One of his latest patents focuses on a MOS transistor apparatus and the method of manufacturing it. This invention addresses the challenges associated with using polycrystalline silicon germanium films for gate electrodes in MOS transistor apparatuses. The reliability of the gate insulating film has been a concern due to stress in the silicon germanium grains. To overcome this issue, Nishitani's method involves forming a polysilicon germanium film after creating silicon fine particles of particle size 10 nm or less on an oxide film. This innovative approach allows for the creation of a high-speed MOS transistor apparatus that utilizes an ultra-thin oxide film with a thickness of 1.5 nm or less. The uniform Ge concentration of the polycrystalline silicon germanium at its interface with the oxide film reduces stress in the film, thereby enhancing the reliability of the gate electrode.
