Latest Patents

Naitoh holds a patent for a "Direct imaging type SIMS instrument having TOF mass spectrometric mode." This invention discloses a direct imaging type SIMS (secondary ion mass spectrometry) instrument that features a mass analyzer comprising superimposed fields. The superimposed fields consist of a toroidal electric field and a uniform magnetic field that is substantially perpendicular to the electric field. In imaging mode, an ion image of the region of a sample, which is irradiated with a primary beam, is focused onto a two-dimensional ion detector by the mass analyzer. In TOF (time-of-flight) mass spectrometric mode, the intensity of the magnetic field is reduced to zero, allowing the use of only the electric field. Pulsed secondary ions from the surface of the sample are then passed through the electric field and separated according to mass over time, based on the principles of TOF mass spectrometry.
