Title: Wataru Andoh: Innovator in Semiconductor Technology
Introduction
Wataru Andoh is a prominent inventor based in Niigata, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 7 patents. His work focuses on improving the manufacturing processes and efficiency of semiconductor devices.
Latest Patents
One of Wataru Andoh's latest patents is a method of manufacturing an insulated gate semiconductor device. This innovation involves a gate electrode that includes a first polysilicon film remaining on a first oxide film, with a part of a second polysilicon layer superimposed on the first. The design ensures that the thickness of the gate electrode on the first gate oxide film matches that of prior art, while the thickness on the second gate oxide films is reduced. This advancement leads to smaller height gaps between the gate electrode and the N+ type source and drain layers, enhancing the flatness of the interlayer oxide film.
Another notable patent is related to the manufacturing of a semiconductor integrated circuit using the LOCOS technique. In this process, an element isolation film is formed with an underlying buffer layer of an oxidation-resisting film. The use of a pad oxidation film and pad poly-Si film allows for a reduction in manufacturing steps and helps to relax the level difference between the gate electrode and the wiring on the element isolation film.
