With a total of 4 patents to his name, Nishimura's work has had a lasting impact on the industry.

Latest Patents

One of his latest patents is the "Ion Implant Apparatus." This innovative apparatus forms ions from an ion source into an ion beam, which is then implanted into a target through an ion beam introduction tube. The design includes radiation means for radiating an electron beam, which is fixed on the ion beam introduction tube. The target reflects the electron beam to generate a reflectance beam, while also preventing the reflectance beam and secondary electron beam from directly radiating onto the target to be ion-implanted. This technology helps maintain high energy electrons away from the wafer surface, preventing negative charging and reducing measurement errors in dopant atom counts.

Another notable patent is the "Fuse Element for Integrated Circuit Memory Device." This fuse element is prepared from polycrystalline silicon and is deposited on an insulating layer on the main surface of a semiconductor substrate. The design features connecting portions with stepped surfaces that ensure tight contact with the insulating layer, enhancing the reliability of the integrated circuit memory.
