Title: Tatsuya Yamauchi: Innovator in Semiconductor Technology
Introduction
Tatsuya Yamauchi is a prominent inventor based in Nobeoka, Japan. He has made significant contributions to the field of semiconductor technology, holding two patents that showcase his innovative approach to device production.
Latest Patents
Yamauchi's latest patents focus on a semiconductor device and its production method. The process involves a silicon substrate where a silicon oxide film is applied. A polycrystalline silicon film is then formed using a low-pressure CVD method at a monosilane partial pressure of no more than 10 Pa and a film formation temperature of no lower than 600°C. The polycrystalline silicon film is doped with impurities, such as phosphorus, to create a phosphosilicate glass film. After the removal of this film, the polycrystalline silicon undergoes thermal oxidation in an oxidative atmosphere to form a dielectric film on its surface. An oriented polycrystalline silicon film is then created, which serves as both the upper and lower electrodes in a semiconductor device featuring a capacitor. This innovative method allows for the rapid production of thin-film transistors with high dielectric strength.
