His innovative work focuses on methods and apparatuses that enhance the efficiency and accuracy of substrate processing in high vacuum environments.

Latest Patents

One of Iizuka's latest patents is a "Method and apparatus for processing fine particle dust in plasma." This invention addresses the challenges of processing particulate dust when a substrate is placed in a high vacuum enclosure. The apparatus generates plasma within this enclosure and introduces a reactive material to process the substrate. It features at least one collecting electrode positioned around the substrate, which efficiently removes particulates generated in plasma by applying a predetermined electric potential. This innovation effectively resolves issues related to deposition on the inner walls of the vacuum enclosure and improves processing accuracy and film quality.

Another notable patent is the "Plasma generation apparatus," which aims to generate high-density plasma even at the center of the plasma generation region. This apparatus includes a vacuum vessel, gas induction unit, exhaust unit, cylindrical discharge electrode, high-frequency oscillators, and ring-shaped permanent magnets. The design of the discharge electrode encloses the plasma generation region, while the magnetic force lines created by the permanent magnets are configured to enhance plasma density without intersecting the walls that define the plasma generation area.
