Latest Patents

Nishimoto's latest patents include a method for producing a semiconductor device that involves smoothing the edges of a window through a phosphosilicate glass (PSG) film. In this method, a masking film is placed under the PSG film to prevent impurities from penetrating the semiconductor substrate during the heating process. This innovative approach allows for the enhancement of the properties of a metal-insulator-semiconductor (MIS) device, as the masking film does not inhibit the penetration of hydrogen gas.

Another notable patent by Nishimoto focuses on producing a semiconductor device with a protecting glass film that contains impurities of a first conductivity type. In this process, a masking film is formed on the surface of a region of a second conductivity type, which is opposite to the first. This masking film prevents impurities from the protecting glass film from entering the semiconductor substrate during the heating treatment, ensuring the integrity of the device.
