With a total of six patents to his name, Oda has consistently contributed innovative solutions that enhance the manufacturing processes within the semiconductor industry.

Latest Patents

Among his latest inventions is a "Dispersion containing Cu ultrafine particles individually dispersed therein." This dispersion comprises an organic solvent that is resistant to evaporation at room temperature yet can evaporate during the drying-firing process. This feature is beneficial when forming Cu-distributing wires on a semiconductor substrate. The ultrafine Cu particles, with sizes no greater than 0.01 µm, are encapsulated by the organic solvent and remain separately dispersed to achieve a viscosity not exceeding 50 cP at 20 °C. This invention allows for complete filling of fine wiring grooves, via holes, and contact holes of LSI substrates, ensuring a conductive, uniform, and fine pattern on the substrate.

Another notable patent is the "Method for forming Cu-thin film." This method involves coating a semiconductor substrate, which includes recessed portions such as wiring grooves and via holes with an aspect ratio of 1 to 30, with the aforementioned dispersion. The substrate is then fired in an atmosphere that decomposes the organic substances without oxidizing the Cu, allowing for the development of a Cu-thin film in the recessed areas. This innovative approach not only facilitates the precise embedding of Cu-thin films in high aspect ratio structures but also minimizes processing costs.
