Title: The Innovations of Toshimoto Kubota

Introduction

Toshimoto Kubota is a notable inventor based in Kyoto, Japan. He holds two patents that showcase his contributions to the fields of display technology and semiconductor memory devices. His work has significantly impacted the way we interact with electronic displays and memory storage.

Latest Patents

One of his latest patents is for a plasma display panel with a light-shielding layer. This innovative panel can display high-quality videos while reducing manufacturing steps. The design features a pair of substrates that confront each other to create a dischargeable space in between. The front substrate is transparent and includes display electrodes formed of scan and sustain electrodes, along with light-blocking sections corresponding to non-dischargeable areas. The rear substrate contains phosphor layers that emit light when discharged. Each display electrode is composed of transparent and bus electrodes, with at least one layer made of a black material that has specific volume resistance properties.

Another significant patent by Kubota is a method for fabricating a nonvolatile semiconductor memory device. This method involves a stacked gate portion that includes a tunnel insulating film, a floating gate electrode, a capacitive insulating film, and a control gate electrode, all formed over a p-type silicon substrate. The structure improves drain-disturb characteristics during writing by applying an electric field between the floating gate electrode and the drain.
