摘要:
Disclosed herein are devices, systems and methods for in-line, nanoscale metrology. One system comprises monolithic flexure mechanisms with integrated actuators that allow movement and positioning in two axes, with an extremely high degree of accuracy, of a structure comprising one or more scanning probes. This structure is suspended to prevent any destructive interference from a sample, which can be stationary or moving at a nonzero rate, and rigid or flexible in mechanical behavior. This system can be activated at startup and quickly actuate the structure to approach the surface of the sample. Once the system achieves the desired proximity between the one or more probes and the sample, the system maintains that position of the structure to a high degree of accuracy regardless of any disturbances. This array can be moved at varying speeds laterally to match the velocity of any continually moving substrates, thus enabling scanning of moving substrates.
摘要:
A method for interrogating a surface using scanning ion conductance microscopy (SICM), comprising the steps of: a) repeatedly bringing a SICM probe into proximity with the surface at discrete, spaced locations in a region of the surface and measuring surface height at each location; b) estimating surface roughness or other characteristic for the region based upon the surface height measurements; and c) repeatedly bringing the probe into proximity with the surface at discrete, spaced locations in the region, the number and location of which is based upon the estimated surface roughness or other characteristic in the region, and obtaining an image of the region with a resolution adapted to the surface roughness or other characteristic.
摘要:
It is difficult for a scanning probe microscope according to the conventional technology to operate a probe for scanning and positioning in a wide range and for high-precision scanning in a narrow range. A scanning probe microscope according to the invention uses probe driving actuators for coarse adjustment and fine adjustment. For scanning and positioning in a wide range, the coarse adjustment actuator is switched to fast responsiveness. For scanning in a narrow range, the coarse adjustment actuator is switched to slow responsiveness. Instead, positional noise is reduced and the fine adjustment actuator is mainly used for scanning in a narrow range. The probe is capable of not only scanning and positioning in a wide range but also high-precision scanning in a narrow range.
摘要:
A shape measuring method for measuring a shape of a surface of an object. The method includes a first measuring step for measuring the surface of the object by detecting light from the object, and a second measuring step for measuring the surface of the object by relatively scanning a probe and the object. A scanning speed changes on the basis of the result of the first measurement step.

A scanning probe microscopy (SPM) inspection and/or modification system which uses SPM technology and techniques. The system includes various types of microstructured SPM probes for inspection and/or modification of the object. The components of the SPM system include microstructured calibration structures. A probe may be defective because of wear or because of fabrication errors. Various types of reference measurements of the calibration structure are made with the probe or vice versa to calibrate it. The components of the SPM system further include one or more tip machining structures. At these structures, material of the tips of the SPM probes may be machined by abrasively lapping and chemically lapping the material of the tip with the tip machining structures.

An information processing apparatus, which utilizes a physical phenomenon occurring between a probe and a sample to detect information from the sample, includes a device for moving the probe in order to adjust a clearance between the probe and the sample, a device for detecting a physical phenomenon occurring between the probe and the sample, a device for generating a control signal for the moving device to change the clearance between the probe and the sample to a desired clearance, based on a result of detection of the detecting device, and a device for applying an offset signal to the control signal in order that the probe can move with respect to a reference located at a position deviated from a center position of a movable range of the probe by means of the moving device.
摘要:
A large scale horizontal translation stage for a microscope or other instrument particularly a scanning probe microscope is disclosed. The translation stage is provided with air bearings which allow it to float over a planar surface. The translation stage is kinematically mounted on a guiding member such that the horizontal position of the translation stage is defined by the guiding member but the translation stage is free to move in a direction perpendicular to the planar surface. To position a sample, the air bearings are actuated and the guiding member moves the translation stage to a desired position. An attractive force, preferably suction in the air bearings, is then applied to hold the translation stage firmly against the supporting surface while the sample is analyzed. The preferred embodiment includes two optical microscopes. The first optical microscope is directed substantially perpendicular to the plane of the sample and has a focal point which coincides with the surface of the sample when it is being positioned by the translation stage. The second optical microscope is directed obliquely and focused on the probe.

A micromanipulator for the movement of an object relative to a treatment or analyzing position so that at least a part of the surface of the object can be treated or analyzed. The micromanipulator possesses a plurality of kinematic elements which support the object or an object holder and which, for this purpose, are equipped with a support for the object or the object holder. For the implementation of micromovements, the kinematic elements are piezo-electrically displaceable. The object is supported on at least one of the kinematic elements in such a manner that there can also be concurrently implemented micromovement and macromovements normal to the treatment or analysis plane of the object.
