The high precise technology of our thickness
gauges determine the film thickness of even sub-micron structures, for instance, of
Vapor Deposition Layers (like Parylene) or Photo Resist
The picture shows a 3D film thickness profile of a 10 mm˛ diamond layer on silicon in the
thickness range of 0,8-1 microns. Each color maps a thickness range of only 12 nanometer.
Note the microstructures on the plateau of the diamond layer!
