  • Patent number: 7388199
    Abstract: A probe is made by attaching a carbon nanotube 12 to a mounting base end 13, which eliminates the effects of a carbon contamination film, to increase the bonding strength, increase the conductivity of the probe, and strengthen the bonding performance thereof by coating the entire circumference of the nanotube and the base with a coating film, rather than coating just one side. The work of mounting the carbon nanotube and mounting base end are performed under observation by a microscope. Further, the carbon contamination film 14 formed by an electron microscope is stripped off at a stage before bonding by the coating film.

  • Patent number: 7350404
    Abstract: The probe tip movement control method of the scanning probe microscope is used for a scanning probe microscope provided with a cantilever 21 having a probe tip 20 facing a sample 12. The atomic force occurring between the probe tip and sample is measured when the probe tip scans the surface of the sample. X-, Y-, and Z-fine movement mechanisms 23, 29, and 30 are used to relatively change the positions of the probe tip and sample. It is possible to maintain a high measurement accuracy and enable scan movement of a probe tip on a sample surface by simple control when measuring a part having a gradient in measurement of an uneven shape on a sample surface.

    Abstract: A surface inspection apparatus and a method for inspecting the surface of a sample are capable of inspecting discriminatingly between scratches of various configuration and adhered foreign objects that occur on the surface of a work target when the work target (for example, an insulating film on a semiconductor substrate) is subjected to a polishing process such as CMP or a grinding process, in semiconductor manufacturing process or magnetic head manufacturing process. In the invention, the scratch and foreign object that occur on the polished or ground surface of the sample is epi-illuminated and slant-illuminated by use of approximately same light flux, the difference between the scattered light intensity from the shallow scratch and from the foreign object is applied to thereby discriminate between the shallow scratch and the foreign object, and the directionality of the scattered light is detected to discriminate between the linear scratch and the foreign object.
