Patents by Inventor Takeshige Tanigaki

Takeshige Tanigaki has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 6456690
    Abstract: An X-ray generator, an X-ray inspector and an X-ray generation method capable of automatically focusing an energy beam, such as an electron beam for generating an X-ray, on a target are provided. The generation, inspector and the method have been developed by turning an attention on the fact that convergence conditions of an electron beam has a close relationship with a temperature on a surface of an X-ray tube target. The method comprises the steps of measuring the temperature changes at real time by a temperature sensor 14 and automatically controlling a current value of a focusing coil 6.
    Type: Grant

  • Patent number: 5637870
    Abstract: A method of analysis of the distribution of concentration of a substrate including: a step of preparing a plurality of types of sample substrates whose distribution of concentration is to be analyzed; a step of forming on the surfaces of those substrates dummy films of a material different from the substrates or etching the surfaces of the plurality of sample substrates to different depths; in the case of the dummy films; a step of introducing into the sample substrates specific impurities from the direction of the dummy films under substantially identical conditions and then a step of removing the dummy films; a step of performing mass analysis from the sides of the sample substrates; and a step of sequentially calculating the difference in the results of the mass analysis among the sample substrates.

  • Patent number: 5350919
    Abstract: A quantitative analyzing method by a secondary ion mass spectrometric method comprises the steps of: quantitatively analyzing the target element by the secondary ion mass spectrometric method with respect to a plurality of ion-implanted standard samples, while changing an implantation energy; and correcting a secondary ion intensity which is obtained with respect to the target element in the surface layer of the sample to be analyzed by the secondary ion mass spectrometric method on the basis of the results of the quantitative analyses with respect to the plurality of standard samples. A secondary ion mass spectrometer having such a function is also disclosed.
