Latest Patents

Ogata holds a patent for a method of manufacturing a semiconductor device with a capacitor and a transistor. This invention aims to prevent dielectric breakdown of a capacitor in a semiconductor device that has both a capacitor and a MOS transistor formed on the same semiconductor substrate. The process involves forming a SiO film as a gate insulation film on a P-type semiconductor substrate. A photoresist layer is selectively applied in the high voltage MOS transistor formation region, allowing for precise etching that protects the edges of trench isolation films adjacent to the capacitor formation region. This innovative approach ensures that the capacitor insulation film is effectively formed without compromising the integrity of the device.
