System Information

General Description

The Filmetrics is used to measure the thickness and optical constants (n and k) of transparent and semi-transparent thin film such as oxides, nitrides, resists, polyimides, polysilicon. The Filmetrics measures film characteristics by reflecting light and then analyzing this light over a range of wavelengths.


Measured films should be optically smooth. Very rough films and opaque films can not be measured.

  • Thickness Measurement Range: nm to micron range
  • Optical Constant Measurement Range: 1000A and 10um
  • Thickness Accuracy: +/- 1nm at 500nm
  • Wavelength Range: 400nm to 1000nm
