Photospectrometer, Filmetrics F40 - Status: Available
|
The Filmetrics F40 is used to measure the thickness and optical constants (n&k) of dielectric and semiconductor thin films. Measured films must be optically smooth and within the range of 30A to 40um.Transmission-vs- wavelength can also be measured if substrate is transparent. Commonly measured films include nitrides, oxides, photoresists, polysilicon, polyimides, cell gaps, etc.
