Latest Patents

Morimoto is credited with 1 patent: “Target for Cathode Discharging Arc Ion Plating and Method of Manufacturing the Same.” The invention concerns a target containing aluminum and chromium. It limits the thickness of the aluminum-chromium compound layer between chromium particles and aluminum to 30 micrometers or less. Alternatively, it limits the combined X-ray diffraction peak intensity of the aluminum-chromium compound to 10% or less of the total peak intensity for aluminum, chromium, and the compound. The target also has a relative density of at least 92%. These specifications are intended to reduce uneven arc-spot movement and the formation of macroparticles, helping produce high-quality hard films.

Career Highlights

Morimoto’s listed invention reflects work on materials and manufacturing processes for arc ion plating. The patent focuses on target composition and density as factors in controlling deposition performance and film quality.
