  • Publication number: 20190064211
    Abstract: A scanning probe microscope has a probe configured to move across the surface of a sample to be monitored. A scanner, to which the probe is mounted, moves the probe across the sample surface such that the probe is deflected in accordance with the structure of the sample surface. A beam system directs a light beam at the probe during the movement of the probe across the sample surface and a detector monitors the deflection of the probe using the light beam. The arrangement is such that the scanner is physically independent of the beam system.

  • Patent number: 8087288
    Abstract: A scanned-stylus atomic force microscope (AFM) employing the optical lever technique, and method of operating the same. The AFM of the invention includes a light source and a scanned optical assembly which guides light emitted from the light source onto a point on a cantilever during scanning thereof. A moving light beam is thus created which will automatically track the movement of the cantilever during scanning. The invention also allows the light beam to be used to measure, calibrate or correct the motion of the scanning mechanism, and further allows viewing of the sample and cantilever using an optical microscope.

  • Patent number: 7102761
    Abstract: An interferometry method includes: imaging test light reflected from at least a first portion of a test surface to interfere with reference light on a camera and form an interference pattern, wherein the imaging defines a depth of focus for the light reflected from the test surface, and wherein the test light and reference light are derived from a common source; varying an optical path length difference between the test light and reference light over a range larger than the depth of focus, wherein the optical path length difference corresponds to a difference between a first optical path between the common source and the camera for the test light and a second optical path between the common source and the camera for the reference light; and maintaining the first portion of the test surface within the depth of focus as the optical path length difference is varied.

  • Patent number: 6032518
    Abstract: A scanned-stylus atomic force microscope (AFM) employing the optical lever technique, and method of operating the same. The AFM of the invention includes a light source and a scanned optical assembly which guides light emitted from the light source onto point on a cantilever during scanning thereof. A moving light beam is thus created which will automatically track the movement of the cantilever during scanning. The invention also allows the light beam to be used to measure, calibrate or correct the motion of the scanning mechanism, and further allows viewing of the sample and cantilever using an optical microscope.

  • Patent number: 5705814
    Abstract: A scanning probe microscope and method having automated exchange and precise alignment of probes, wherein one or more additional stored probes for installation onto a probe mount are stored in a storage cassette or a wafer, a selected probe is aligned to a detection system, and the aligned probe is then clamped against the probe mount. Clamping is performed using a clamp which is disabled when removing a replacement probe from the storage cassette, enabled when installing the probe on the probe mount and disabled when releasing the probe at a later time for subsequent probe exchange. Probe alignment is automated using signals from the probe detection system or by forming an optical image of the probe using a camera or similar technique and determining probe positioning using pattern recognition processing of the probe image to allow probe removal and exchange without operator intervention. Techniques for error checking are employed to ensure proper probe installation and operation.
