  • Patent number: 11145484
    Abstract: An analyzing apparatus includes a sample chamber, a measurement apparatus, and a gas cluster ion beam apparatus. A cooling body separates an ionization chamber of the gas cluster ion beam apparatus from a nozzle support to prevent heat emitted by an ionization filament from being transmitted to the nozzle support, and a temperature of a source gas emitted from a nozzle is kept at a constant temperature by a gas heating device while a sputtering rate is kept constant. A pressure of the source gas supplied to the nozzle is kept at constant pressure by a pressure controller, and a size of gas cluster ions is kept at a constant value. Because the sputtering rate is a constant value, highly accurate depth surface profiling can be performed.

  • Patent number: 9372161
    Abstract: Provided are an ion source, an ion gun, and an analysis instrument, which are capable of performing sputtering without damage to a surface of a sample and improving detection sensitivity in mass spectroscopy. In the ion source, an emission opening to which ionization liquid is supplied is disposed in an electric field formed in vacuum environment by an extracting electrode so that super large droplet cluster ions are generated from the emission opening. When the sample is irradiated with a super large droplet cluster ion beam, the sample surface is subjected to sputtering without damage, so as to remove contamination substances or to expose a new surface of the sample. In mass spectroscopy, detection sensitivity is improved.

  • Publication number: 20110064198
    Abstract: The object of the present invention is to analyze a functional organic compound with high accuracy. In the present invention, cluster ions are accelerated so that the kinetic energy of cluster ions is less than 3.1 eV per one atom that makes up the cluster ion and the cluster ions enter a sample. Since the functional organic compound in the sample is etched without the breakdown of the chemical structure, the functional organic compound, which has not been chemically denatured, is exposed on the surface of the sample. By alternately performing the etching and the surface analysis of the sample, or performing the surface analysis of the sample while performing the etching, the sample can be accurately analyzed in the depth direction.

  • Patent number: 7034295
    Abstract: A photoemission electron microscopy having a light source system for carrying out a high-resolution measurement such as work function distribution measurement or magnetic domain distribution with reliability, and a high-sensitivity measurement method using the photoemission electron microscopy. A photoemission electron microscopy having an excitation light source system in which a specimen is irradiated with irradiation light from a light source uses a vacuum chamber in which the specimen is placed and an objective lens which collects the irradiation light on a specimen surface. The objective lens is accommodated in the vacuum chamber. The light source may be placed outside the vacuum chamber. A condenser lens which makes the irradiation light from the light source generally parallel may be placed between the light source and the vacuum chamber. A transmission window which transmits the irradiation light while the vacuum chamber is sealed may be placed between the condenser lens and the objective lens.
