Title: Noriyasu Katagiri: Innovator in Semiconductor Technology
Introduction
Noriyasu Katagiri is a prominent inventor based in Niigata, Japan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to improving production processes.
Latest Patents
One of his latest patents is focused on a semiconductor device that incorporates a capacitance element. The invention aims to shorten the production process of the semiconductor device by utilizing the pad oxide film and the first polycrystalline silicon layer as a stress buffering material during the formation of the element separation oxide film. These materials are not removed and serve as the capacitance insulation film and a portion of the upper electrode of the capacitance element. This innovative approach allows for the omission of the removing process of the pad and polycrystalline silicon layer, as well as the dummy oxidation and its removal process typically seen in conventional methods. Additionally, it addresses the issue of impurity-enhanced oxidation during the formation of the capacitance insulation film.
