Latest Patents

One of Ueno's latest patents involves a semiconductor device that includes an impurity layer with continuous portions formed at different depths. The method of manufacturing this device begins with forming a trench in a substrate, where a silicon oxide film serves as trench isolation. This film maintains its shape without sagging from the main surface of the substrate. A channel impurity layer is then created to control the threshold voltage of a MOSFET, made of a P-type layer with a higher impurity concentration than the substrate. The first portion of this layer is positioned near the trench's opening edge along its side surface, specifically within the N-type layer. A second portion is formed deeper than the first, followed by the formation of a gate insulating film and a gate electrode on the substrate's main surface.
