  • Patent number: 8074293
    Abstract: For adjusting a positional relationship between a specimen and a probe to measure an electric characteristic of the specimen through a contact therebetween, a base table holding a specimen table holding the specimen and a probe holder holding the probe is positioned at a first position to measure the positional relationship between the probe and the specimen at the first position, and subsequently positioned at a second position to measure the positional relationship therebetween at the second position so that the probe and the specimen are contact each other at the second position, the specimen table and the probe holder are movable with respect to each other on the base table at each of the first and second positions to adjust the positional relationship between the probe and the specimen, and a measuring accuracy at the second position is superior to a measuring accuracy at the first position.

  • Patent number: 7271385
    Abstract: An inspection method and an inspection apparatus using an electron beam enabling more detailed and quantitative evaluation at a high throughput level. The method comprises the steps of irradiating, based on previously prepared information concerning a defect position on the surface of a sample, the defect and its vicinity with an electron beam a plurality of times at predetermined intervals; detecting an electron signal secondarily generated from the sample surface by the electron beam; imaging an electron signal detected by the previously specified n-th or later electron beam irradiation; and measuring the resistance or a leakage amount of the defective portion of the sample surface in accordance with the degree of charge relaxation by monitoring the charge relaxation state of the sample surface based on the electron beam image information.

  • Publication number: 20060247355
    Abstract: To provide an insulating and thermally conductive resin composition from which a molded article having a high insulating properties and a high thermal conductivity can be produced and which is excellent in moldability, a molded article, and a method of producing the resin composition. The insulating and thermally conductive resin composition of the invention includes at least 30% by volume or more of a thermoplastic resin, 10 to 40% by volume of metallic aluminum type filler, and 5 to 25% by volume of a flame retardant. Particularly, addition of 1 to 10% by volume of a metal powder having a melting point of 500° C. or higher and 1 to 10% by volume of a low melting point alloy having a melting point of 500° C. or lower can provide more isotropic thermal conduction.

  • Patent number: 7129727
    Abstract: A defect inspecting apparatus in which a plurality of probes to measure electric characteristics of a sample including a fine wiring pattern are combined with a charged-particle beam unit includes graphic user interfaces (GUI) to simply control the plural probes. The apparatus includes a probe image processing unit to display the plural probes on a display; a selecting unit to select, from the probes displayed on the display, a probe to be operated; and a display unit to simultaneously display the probe selecting unit and information indicating that the selected probe is an operable probe, or the probe is in a non-selected state.
