    摘要: A dual stage scanning instrument includes a sensor (60) for sensing a parameter of a sample (90) and coarse and fine stages (80,70) for causing relative motion between the sensor (60) and the sample (90). The coarse stage (80) has a resolution of about 1 micrometer and the fine stage (70) has a resolution of 1 nanometer or better. The sensor (60) is used to sense the parameter when both stages cause relative motion between the sensor assembly (60) and the sample (90). The sensor (60) may be used to sense height variations of the sample surface as well as thermal variations, electrostatic, magnetic, light reflectivity or light transmission parameters at the same time when height variation is sensed. By performing a long scan at a coarser resolution and short scans at high resolution using the same probe tips at fixed relative positions, data obtained from the long and short scans can be correlated accurately.

    摘要: A head for the linear dimension checking of mechanical pieces including a casing, an arm carrying a feeler for touching a surface of the mechanical piece to be checked, a fulcrum, coupled to the casing and the arm, for enabling displacements of the arm with respect to the casing and a transducer for providing signals depending on the position of the arm with respect to the casing. The head has specific flexibility and modularity features, thanks to the possibility of operating from the exterior for adjusting and replacing various components. The transducer is of the inductive, half-bridge type, with multiple windings. An integral element for the electric connection to a processing unit includes the windings of the transducer, a cable and a connector, and the latter comprises a rapid locking/unlocking device. The ends of the cable are connected between the windings of the transducer and the connector by means of an over-moulding process of a plastic material. A checking apparatus, including at least a gauging or measuring head, includes a stationary structure and at least a support structure for the head, coupled to the stationary structure in an adjustable and removable way.

    摘要: A probe-based surface characterization or metrology instrument accounts for errors in the vertical positioning of its probe and errors in detecting the vertical position of its probe. These errors are accounted for by subtracting reference scan data from measurement scan data. The measurement scan data is obtained from an area that includes the feature of interest as well as a portion of a reference area that includes the feature of interest, as well as a portion of the reference area which is featureless. The reference scan data is obtained from an area that includes the reference area and that, preferably, excludes the features of interest. This procedure is particularly well-suited for measuring pole tip recession in a magnetic head.

    摘要: A topographic head (100) for profilometry and AFM supports a central paddle (108) by coaxial torsion bars (104) projecting inward from an outer frame (102). A tip (118) projects from the paddle distal from the bars. The torsion bars include an integrated paddle rotation sensor (142). An XYZ stage (200) may carry the topographic head for X, Y and Z axis translation. The XYZ stage's fixed outer base (202) is coupled to an X-axis stage (204) via a plurality of flexures (206). The X-axis stage is coupled to a Y-axis stage (212) also via a plurality of flexures (214). One of each set of flexures includes a shear stress sensor (222). A Z-axis stage (238) may also be included to provide an integrated XYZ scanning stage. The topographic head's frame, bars and paddle, and the XYZ stage's stage-base, X-axis, Y-axis and Z-axis stages, and flexures are respectively monolithically fabricated by micromachining from a semiconductor wafer (252a, 252b, 262).
