Latest Patents

Maruyama's latest patents include a semiconductor device that features a field plate on an insulating film covering a transistor. This field plate is electrically coupled to the gate of the transistor via the insulating film. The transistor is situated on a substrate, with a silicon nitride protective film covering both the insulating film and the field plate. Additionally, a silicon oxide base film is placed on the silicon nitride protective film, and a MIM capacitor is positioned on the silicon oxide base film. The MIM capacitor consists of a first electrode, a dielectric film, and a second electrode, which are stacked in a specific order. The formation of the MIM capacitor involves wet etching on the silicon oxide base film after the dielectric film is created.

Another notable patent is a method of manufacturing a semiconductor device. This method includes the formation of a field plate on an insulating film that covers a transistor, which is also electrically coupled to the gate of the transistor via the insulating film. The process involves creating a silicon nitride protective film over the insulating film and field plate, followed by the formation of a silicon oxide base film on the protective film. The MIM capacitor is then formed on the silicon oxide base film, with the same structural components as mentioned in the previous patent.
