WAFER FLATNESS MEASUREMENTS
Patented non-contact Optical Interferometer for measuring flatness of thin, transparent wafers, windows and substrates by interferometric comparison to an optical reference flat. Unlike with Fizeau Interferometer, the need for an application of film on the backside of thin transparent wafers has been eliminated.
