Abstract

An apparatus and method for scanning a probe over a surface to either produce a measurement of the surface representative of a parameter other than the topography of the surface or to perform a task on the surface. The scanning operation is divided into two parts and with a first scan to obtain and store topographical information and with a second scan to measure the parameter of the surface other than topography or to perform the task while the probe height is controlled using the stored topographic information.
