Patent number: 8495759Abstract: Provided is an aligning method capable of setting a sample observation unit such as an optical microscope to a probe microscope observation position at high precision. A sample having a known structure is used in advance. A surface of the sample and a shape of a cantilever provided with a probe are observed using the sample observation unit such as the optical microscope. A sample observation position and a probe position which are obtained using the sample observation unit are verified, and a relative positional relationship therebetween is recorded. Then, a first mark indicating a position of the cantilever and a second mark which is displayed in conjunction with the first mark and has the relative positional relationship with the first mark are produced to align the sample relative to the second mark.Type: GrantFiled: July 28, 2009Date of Patent: July 23, 2013Assignee: SII NanoTechnology Inc.Inventors: Shigeru Wakiyama, Hiroyoshi Yamamoto, Yoshiteru Shikakura, Itaru Kitajima

Patent number: 7476418Abstract: In a method for fabricating a nanometer-scale structure by arranging nanotubes in a predetermined direction at a predetermined position, the method for fabricating a nanometer-scale structure comprises a first step of planarizing a substrate by etching a predetermined part by irradiating a focused energy beam to the sample, a second step of decomposing and depositing an organic gas into a columnar structure with an objective of determining the position and direction, and a third step of attaching and fixing the nanotube by using the thus deposited columnar structure as a standard of position and direction.Type: GrantFiled: September 27, 2004Date of Patent: January 13, 2009Assignee: SII NanoTechnology Inc.Inventors: Masatoshi Yasutake, Takashi Kaito, Yoshiharu Shirakawabe, Itaru Kitajima

Patent number: 7373806Abstract: A scanning probe microscope has a probe tip for undergoing a scanning operation to scan a sample surface in X- and Y-directions parallel to the sample surface and for undergoing movement in a Z-direction vertical to the sample surface. A vibration unit vibrates the probe tip at a vibration frequency that resonates with of forcedly vibrates the probe tip. An observation unit collects observational data from the sample surface when the probe tip is in proximity or contact with the sample surface. A detection unit detects a variation in the state of vibration of the probe tip when the probe tip is in proximity or contact with the sample surface during a scanning operation.Type: GrantFiled: August 24, 2004Date of Patent: May 20, 2008Assignee: SII NanoTechnology Inc.Inventors: Itaru Kitajima, Kazutoshi Watanabe, Shigeru Wakiyama, Masatoshi Yasutake, Akira Inoue

Patent number: 7026607Abstract: A scanning probe microscope has a scanner and a mounting unit for supporting the scanner. An identifying mark is disposed on a part of the scanner for representing preselected information corresponding to the scanner. The mounting unit has an interpreting device for interpreting the preselected information represented by the identifying mark. A setting device sets in a controller, for controlling the scanning probe microscope, parameter information corresponding to the scanner probe microscope, parameter information corresponding interpreted by the interpreting device.Type: GrantFiled: April 20, 2004Date of Patent: April 11, 2006Assignee: SII NanoTechnology Inc.Inventors: Itaru Kitajima, Masatsugu Shigeno
