Publication number: 20190064211Abstract: A scanning probe microscope has a probe configured to move across the surface of a sample to be monitored. A scanner, to which the probe is mounted, moves the probe across the sample surface such that the probe is deflected in accordance with the structure of the sample surface. A beam system directs a light beam at the probe during the movement of the probe across the sample surface and a detector monitors the deflection of the probe using the light beam. The arrangement is such that the scanner is physically independent of the beam system.Type: ApplicationFiled: August 31, 2017Publication date: February 28, 2019Inventors: David A.
