Spectroscopic Ellipsometer(Model: JA Woolam M2000)

Spectroscopic Ellipsometer

 

Description Spectroscopic Ellipsometer

Ellipsometry is a powerful tool used for the characterization of thin films and multi-layer semiconductor structures. Ellipsometry measures the change of polarization upon reflection and compares it to a model. The measured signal is the change in polarization as the incident radiation (in a known state) interacts with the material structure of interest (reflected, absorbed, scattered, or transmitted).

Specifications

  • Vacuum holding provision for wafer holding
  • Measurement of optical constants, dielectric constants, film thickness etc
  • Wafer size up to 156 mm X 156 mm
  • Mapping on whole wafer
  • Angle of acquisitions incidence: 45 to 900
