Title: The Innovations of Tadashi Yoshida
Introduction
Tadashi Yoshida is a notable inventor based in Hyogo, Japan. He has made significant contributions to the field of semiconductor technology and hot-water supply systems. With a total of 2 patents, his work reflects a commitment to advancing technology in practical applications.
Latest Patents
Yoshida's latest patents include a method for forming a surface-roughened conductive film on a semiconductor wafer. This innovative process involves treating an amorphous silicon conductive film with hydrofluoric acid to remove a natural oxide film. Following this, a very thin oxide film is formed, with a thickness ranging from 0.5 angstroms to 20 angstroms. The use of silane gas to create a nucleating film, combined with annealing, results in a uniformly roughened surface on the conductive film. His second patent describes a hot-water storage type hot-water supply apparatus that operates under a natural circulation principle. This system maintains a constant temperature of hot water by utilizing a thermal valve that adjusts based on the temperature of the water in the circulation pipe.
