Latest Patents

Tsurugida's latest patents include a method for selectively oxidizing a silicon wafer. This innovative technique involves covering both surfaces of a silicon wafer with silicon nitride films through the intermediary of pad oxide films. The front surface is partially exposed by patterning the films, while the reverse surface is entirely exposed. This allows for simultaneous oxidation of the exposed regions on the front surface and the entire reverse surface, resulting in the growth of silicon dioxide films.

Another significant patent is a method for forming an insulating film and manufacturing integrated circuits. This method effectively inhibits the spontaneous growth of silicon oxide films on silicon substrates and controls film thickness when exposed to atmospheric conditions. By allowing a silicon dioxide layer to grow to a predetermined thickness, the surface can be treated with organic gas or ammonia gas to achieve desired results.
