Abstract: A profiler or scanning probe microscope may be scanned across a sample surface with a distance between them controlled to allow the sensing tip to contact the surface intermittently in order to find and measure features of interest. The distance is controlled so that when the sensing tip is raised or lowered to touch the sample surface, there is no lateral relative motion between the tip and the sample. This prevents tip damage. Prior knowledge of the height distribution of the sample surface may be provided or measured and used for positioning the sensing tip initially or in controlling the separation to avoid lateral contact between the tip and the sample. The process may also be performed in two parts: a fast find mode to find the features and a subsequent measurement mode to measure the features. A quick step mode may also be performed by choosing steps of lateral relative motion to be smaller than 100 nanometers to reduce probability of tip damage.
