Film Thickness Probe
FTPadv - SENTECH Instruments GmbH.
The SE 500adv combines ellipsometry and reflectometry to eliminate the ambiguity of measuring layer thickness of transparent films. It extends the measureable thickness to 25 µm. Therefore the SE 500adv extends the capability of the standard laser ellipsometer SE 400adv especially for analyzing thicker films of dielectrics, organic materials, photoresists, silicon, and polysilicon.
