Latest Patents

One of his latest patents is a method for fabricating a semiconductor device. This innovative device comprises a first well of a first conduction type formed in a semiconductor substrate, along with a second well of a second conduction type formed in the first well. The invention includes a transistor featuring a control gate formed of an impurity region of the first conduction type within the second well, a first impurity diffused layer, and a second impurity diffused layer with a channel region in between. A floating gate electrode is formed on the channel region and the control gate, separated by a gate insulation film. The control gate is buried in the semiconductor substrate, eliminating the need to form it on the floating gate electrode. This design allows for the memory transistor and other transistors to be fabricated using the same process, reducing fabrication steps and costs.

Another notable patent is for a capacitance detection type sensor and its manufacturing method. In this invention, capacitance sensor electrodes are arranged in a matrix form on a semiconductor substrate and coated with a cover film. These electrodes connect to a drive circuit, while ESD electrodes are positioned near the corners of the capacitance sensor electrodes. Each ESD electrode consists of a conductive film, such as aluminum, topped with a TiN film. The ESD electrodes are grounded through the semiconductor substrate, and fine ESD holes are formed on each ESD electrode, reaching from the surface of the cover film.
