Abstract:
A method of scanning a feature with a probe, the probe comprising a cantilever mount, a cantilever extending from the cantilever mount to a free end, and a probe tip carried by the free end of the cantilever. An orientation of the probe is measured relative to a reference surface to generate a probe orientation measurement. The reference surface defines a reference surface axis which is normal to the reference surface and the probe tip has a reference tilt angle relative to the reference surface axis. A shape of the cantilever is changed in accordance with the probe orientation measurement so that the probe tip moves relative to the cantilever mount and the reference tilt angle decreases from a first reference tilt angle to a second reference tilt angle. A sample surface is scanned with the probe, wherein the sample surface defines a sample surface axis which is normal to the sample surface and the probe tip has a scanning tilt angle relative to the sample surface axis. During the scanning of the sample surface the cantilever mount is moved so that the probe tip is inserted into a feature in the sample surface with the scanning tilt angle below the first reference tilt angle.
