One of his key inventions is an ion source and plasma processing apparatus. This invention aims to provide a reliable method for generating stable and long-life plasma. The design includes a high-frequency antenna positioned on the outer side of a dielectric partition wall. This wall separates the plasma generating chamber from a shield body, which also consists of dielectric material. The shield body prevents deposition on the inner surface of the partition wall that faces the high-frequency antenna. This innovative structure minimizes the high-frequency power needed for effective inductive coupling with plasma. The shield body is uniquely designed with a slot that crosses the winding direction of the high-frequency antenna. This arrangement effectively prevents continuous deposition on the inner surface, thereby reducing induction loss between the antenna and the plasma chamber, even when the deposited film is conductive. Saburou Shimizu holds 1 patent for this invention.
