摘要:
A balanced momentum probe holder in an apparatus for characterizing a sample surface has first and second members each having extensible and retractable distal ends. The distal ends extend or retract substantially simultaneously in response to a signal from a detector thus balancing the momentums of the first and second members and reducing the net momentum of the probe holder to essentially zero. Balancing the momentum of the probe holder reduces parasitic oscillations in the apparatus thus enhancing performance.

In a scanning probe apparatus capable of always effectively canceling an inertial force to suppress vibration even in repetitive use while replacing a sample holding table or a probe, a stage for a sample or the probe includes a drive element for moving the sample holding table and movable portions movable in a direction in which an inertial force generated during movement of the sample holding table. The stage is configured so that the drive element, the movable portions, and the sample holding table or the probe are integrally detachably mountable to a main assembly of the scanning probe apparatus.

A quantum beam aided atomic force microscopy and quantum beam aided atomic force microscope that can simultaneously perform atomic-level configuration observation and elemental analysis with the use of an atomic force microscope and further can effect analysis of the chemical state of sample surface and that as being operable in liquids, can realize the elemental analysis and chemical state analysis of biosamples with an atomic-level resolving power. Accordingly, atoms of sample surface are irradiated with quantum beams, such as charged particles, electrons and photons, having a given electron transition energy characteristic of element, and any change in interaction force between the atoms of sample surface having been irradiated with quantum beams and the distal end of the probe is detected.

A scanning probe apparatus for obtaining information of a sample or processing the sample with relative movement between the sample and the apparatus includes a sample stage for holding the sample, and a drive stage with a probe, a cantilever supporting the probe, a cantilever holding member for holding the cantilever, and a drive element for driving the probe in three directions perpendicular to each other. In addition, a movable portion surrounds the drive element and is positioned outside of the drive element, with the movable portion movable in a direction in which an inertial force generated during movement of the probe is canceled. The drive stage includes an optical path, through which light passes, provided inside of the drive stage.

A metrology instrument, such as a probe, probe head, stylus or stylus arm, for mounting on a coordinate position apparatus. The metrology instrument is at least partially constructed from at least one sheet of thermally stable metallic material which is folded to form a three dimensional structure. The at least one sheet of thermally stable material is utilized in the metrology loop of the metrology instrument.
摘要:
A technique for actively damping internal vibrations in a scanning probe microscope is disclosed. The excitation of various mechanical movements, including resonances, in the mechanical assembly of an SPM can adversely effect its performance, especially for high speed applications. An actuator is used to compensate for the movements. The actuator may operate in only the z direction, or may operate in other directions. The actuator(s) may be located at positions of antinodes.
摘要:
A drive stage, for driving a sample or a probe, capable of ensuring a movable range of a movable portion as a counterweight and always effectively canceling an inertial force to suppress vibration of a supporting member leading to vibration of the sample or the probe includes a counter drive element for moving the probe or a sample holding table and a movable portion movable in a direction in which the inertial force generated during movement of the probe or the sample holding table. The movable portion surrounds the counter drive element outside the counter drive element.
摘要:
A scanning probe is microscope has a cantilever having a probe at a disal end thereof and an oscillator for generating a resonance signal near a resonance of the cantilever. A vibrating device receives the resonance signal as a driving signal for vibrating the cantilever. A variable gain amplifier adjusts a gain of displacement signal corresponding to displacement of the vibrating cantilever so as to satisfy the equation G=(A/A0)*G0 to control a quality factor value of the cantilever resonance to an optimal quality factor value, where G represents a gain value of the variable gain amplifer, A represents a preselected oscillation amplitude of the oscillator, A0 represents an initial oscillation amplitude of the oscillator, and G0 represents a gain value of the variable gain amplifier when the initial oscillation amplitude of the oscillator is A0.
