Title: The Innovations of Hisashi Yonemoto: A Pioneer in Semiconductor Technology
Introduction
Hisashi Yonemoto, an accomplished inventor based in Osaka, Japan, has made significant contributions to the field of semiconductor technology. With three patented inventions, his work has revolutionized methods for manufacturing semiconductor devices, particularly in the formation of element isolation films essential for high-voltage transistors.
Latest Patents
Among Hisashi Yonemoto's latest patents is a groundbreaking semiconductor device manufacturing method. This innovative process outlines a formation method of an element isolation film aimed at creating high-voltage transistors with superior characteristics. The method involves several key steps, including the initial formation of a gate oxide film on a substrate, followed by the application of a CMP (Chemical Mechanical Planarization) stopper film. Subsequent etching processes are carried out on both the gate oxide film and the CMP stopper film. The semiconductor substrate is then etched to create a trench. Before filling the trench with a field insulating film, a liner insulating film is strategically formed on the trench's interior wall. This meticulous approach also addresses concerns of void formation in the element isolation film that is laterally positioned with respect to the gate oxide film, ensuring enhanced reliability and performance of the resulting high-voltage transistors.
