Fast spectroscopic ellipsometer M-2000

From Woollam Co.

The M-2000 ellipsometer combines highly accurate 'rotating compensator' method with fast CCD technology. This allows high speed measurements: min. 390 wavelengths in < 1 second. It is available as ex-situ and in-situ setup.

Features
  • Ex-situ, in-situ, or inline
  • Rotating compensator ellipsometer
  • Modular design with variety of options and configurations
  • Maximum spectral range 193 to 1690 nm
  • Fully automated

Further information

The M-2000 utilizes our patented rotating compensator ellipsometer (RCE) technology to achieve high accuracy and precision. The RCE design is compatible with advanced CCD detection to measure ALL wavelengths simultaneously. This ellipsometer collects over 700 wavelengths from the ultraviolet to the near-infrared. With modular optical design, the M-2000 can be attached directly to your process chamber or configured on any of our table-top bases. Advanced design ensures accurate ellipsometry measurements for any sample and includes measurement features like Generalized Ellipsometry, Mueller matrix, and depolarisation.

Applications

Optical constants and thickness, anisotropy, index gradient, composition The M-2000 is an extremely accurate system to determine optical constants, thickness, optical anisotropy, index gradient, composition, etc.
Homogeneity - thickness profile In combination with an automated XY mapping stage, sample homogeneity, thickness profile etc. can be determined with automated measurement recipes
Dynamic measurements - adsorption kinetics Dynamic measurements can be performed either with the in-situ package attached to an UHV deposition chamber or with liquid and heat cells attached to an ex-situ M-2000. Thus, the time-dependent adsorption of molecules out of a liquid ambient can be traced and measured in real-time. Alternatively, temperature-dependent changes of the sample can be determined, like phase-transitions or the glass transition temperature of polymers.
