The Woollam M-2000 spectroscopic ellipsometer is the perfect tool for optically characterizing thin films. The M-2000 is combines rotator and compensator ellipsometry with CCD detection to collect spectra from 255 nm to 1700 nm. most commonly used to measure thin ﬁlm thickness and optical constants. The AEP Core ellipsometer is fully automatic allowing the automatic collection of spectra at multiple angles and multiple locations throughout the samples without additional user intervention. WVase software installed on the control computer enables the modeling of optical constants (n and k) and the film thickness. In addition to optical constants, there are additional material properties that can be extracted from the model such as carrier concentration and surface roughness.
The M-2000 can handle samples as small as 3 mm squares up to Gen-II display glass substrates (370 mm X 470 mm).
Additional licenses of WVase and CompleteEase are available separate from the ellipsometer control computer to enable analysis of spectra outside of the cleanroom. Please inquire via a service request if you would like access to this opportunity. Please be aware that CompleteEase models need to be converted to WVase to be utilized in the automatic measurement routine for the ellipsometer.
