摘要:
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.

摘要:
A scanning probe microscope has a cantilever with a probe facing a sample and a measurement section for measuring a physical quantity occurring between the probe and the sample when the probe scans a surface of the sample, holding the physical quantity constant to measure the surface of the sample. The above microscope further has a probe tilt mechanism, an optical microscope etc. for detecting a position of the probe when the probe is tilted, and a control section for setting the probe in a first tilt posture and second tilt posture, measuring a surface of the sample by the measurement section at each tilt posture, detecting the position of the probe at least at the second tilt posture by the optical microscope etc., and making a measurement location at the second tilt posture match with a measurement location at the first tilt posture for measurement.

摘要:
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.
摘要:
A probe replacement method for a scanning probe microscope for measuring the surface of a sample, having a cantilever (21) having a probe (20), and a measurement unit for measuring a physical quantity between the probe and sample. The scanning probe microscope is provided with a cantilever mount (22), a cantilever cassette (30), an XY stage (14) and Z stage (15) for moving the cantilever cassette, and an optical microscope (18). In a first step, a cantilever is selected from the cantilever cassette and is mounted on the cantilever mount. In a second step, an optical microscope is moved and the mounted cantilever is set in a prescribed position in the field of view after the cantilever is mounted in the scanning probe microscope. In the second step, a step is provided for moving the optical microscope side or the cantilever side and performing positional adjustment.

A fine movement mechanism unit is configured by a supporting member, two fixed sections fixed to this supporting member, two pairs of parallel-plate flexural sections disposed between the two fixed sections, an X fine movement mechanism, a Y fine movement mechanism, and a Z fine movement mechanism. The X fine movement mechanism has an X moving section movable in an X direction, connected to each of the two fixed sections through the two pairs of parallel-plate flexural sections, and two X direction piezoelectric actuators causing the X moving section to move. The Y fine movement mechanism arranged to the X moving section, has other two pairs of parallel-plate flexural sections, a Y moving section movable in the Y direction, connected to the X moving section through the other two pairs of parallel-plate flexural sections, and two Y direction piezoelectric actuators causing the Y moving section to move relatively to the X moving section. The Z fine movement mechanism arranged to the Y moving section, has a Z moving section movable in a Z direction perpendicular to both of the X and Y directions, and a Z direction piezoelectric actuator causing the Z moving section to move.
摘要:
A scanning probe microscope is provided with a probe tip directed to a sample surface, an XYZ fine movement mechanism for providing a relative positional change between the sample and the probe tip, and a displacement detecting section for detecting the displacement of the probe tip. The scanning probe microscope measures the surface characteristic of the sample by using a control signal. This control signal is generated on a signal outputted from the displacement detecting section and is used for keeping a state of a mutual action generated between the sample and the probe tip identical to a predetermined state, while the probe tip scans the surface of the sample based on the operation of the XYZ fine movement mechanism. Further, it comprises a moving section arranged on a standard surface of a microscope stage, which has the sample on an upper surface and moves along the standard surface based on a static pressure guide, a height-position control section for selectively supplying high-pressure fluid to the moving section so as to carry out the static pressure guide and controlling the height-position of the moving section to the standard surface, and an actuating mechanism for moving the moving section in directions parallel to the standard surface.
