Latest Patents

Hashimoto's latest patents include a semiconductor device manufacturing method that enhances the formation of element isolation films. This method allows for the creation of high-voltage transistors with excellent characteristics. The process begins with the formation of a gate oxide film on a substrate, followed by the application of a CMP stopper film. After etching these films, the semiconductor substrate is etched to create a trench. Before filling the trench with a field insulating film, a liner insulating film is formed on the trench's interior wall. This innovative approach prevents the formation of voids in the element isolation film, which is positioned laterally with respect to the gate oxide film.
