Patent number: 9527732Abstract: In certain embodiments, a probe scans a surface to produce a first scan. The first scan is used to estimate a vertical offset for scanning the surface to produce a second scan. In certain embodiments, an AFM device engages a probe to a surface using a piezo voltage.

Patent number: 9150415Abstract: A topographic profile of a structure is generated using atomic force microscopy. The structure is scanned such that an area of interest of the structure is scanned at a higher resolution than portions of the structure outside of the area of interest. An profile of the structure is then generated based on the scan. To correct skew and tilt of the profile, a first feature of the profile is aligned with a first axis of a coordinate system. The profile is then manipulated to align a second feature of the profile with a second axis of the coordinate system.Type: GrantFiled: July 25, 2008Date of Patent: October 6, 2015Assignee: Seagate Technology LLCInventors: Lin Zhou, Huiwen Liu, Dale Egbert, Jonathan A.

Patent number: 8525112Abstract: 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.Type: GrantFiled: August 10, 2010Date of Patent: September 3, 2013Assignee: Seagate Technology LLCInventors: Lin Zhou, Huiwen Liu, Dale Egbert, Peter Gunderson, John Ibele
