MgO Thinkness Measurement for PDP

This Spectroscopic Reflectometer is optimized for the in-line monitoring of MgO films which are used as the protection layer of PDP cell. Ellipso Technology has the unique and advanced technology of m-FFT software combined with pseudo substrate analysis technique for the accuracy and fast measurement of MgO film thickness on top of the thick dielectrics and patterned substrates. This instrument is equipped with multiple probes so that it is best suited to monitor film thickness of large-size samples with dielectrics and/or patterns.

◈ PERFORMANCE
