Title: Innovations by Kenichi Oto: A Trailblazer in Semiconductor Technology
Introduction
Kenichi Oto, an inventive force located in Tokyo, Japan, has made significant contributions to the field of semiconductor technology. With a total of four patents to his name, Oto's work is characterized by a focus on nonvolatile semiconductor memory devices that push the boundaries of performance and reliability.
Latest Patents
Among his latest patents, Oto has developed a groundbreaking nonvolatile semiconductor memory device. This invention features a sub-decoder element corresponding to each word line, constructed using the same conductive type MOS transistors. The sub-decoder elements are meticulously arranged in columns, with the layout of active regions inverted in the Y direction and each displaced by one sub-decoder element in the X direction. Such a configuration ensures that high voltage does not get applied to both gate electrodes adjacent in the Y direction. To further enhance performance, a well voltage for the sub-decoder element group is calibrated so that the source to substrate of the transistor remains in a deep reversed-bias state. This innovative design effectively suppresses leakage by parasitic MOS transistors in sub-decoder and word line driving circuits, which operate under positive or negative high voltage conditions.
