  • Variable pixel density imaging
    Patent number: 8525112
    Abstract: A method and associated apparatus for topographically characterizing a workpiece. The workpiece is scanned with a scanning probe along a first directional grid, thereby scanning a reference surface and an area of interest subportion of the reference surface, at a variable pixel density including a first pixel density outside the area of interest and a second pixel density inside the area of interest to derive a first digital file characterizing topography of the workpiece. The workpiece is further scanned along the reference surface and the area of interest with the scanning probe along a second directional grid that is substantially orthogonal to the first directional grid and at a constant pixel density to derive a second digital file characterizing topography of the workpiece. A processor executes computer-readable instructions stored in memory that generate a topographical profile of the workpiece in relation to the first and second digital files.

  • Scanning probe microscopy employing correlation pattern recognition
    Patent number: 8371155
    Abstract: An apparatus and associated method for topographically characterizing a workpiece. A scanning probe obtains topographical data from the workpiece. A processor controls the scanning probe to scan a reference surface of the workpiece to derive a first digital file and to scan a surface of interest that includes at least a portion of the reference surface to derive a second digital file. Correlation pattern recognition logic integrates the first and second digital files together to align the reference surface with the surface of interest.
