Spectroscopic ellipsometry and reflectometry: a user's perspective. Abstract: We discuss how analytical tools in a characterization lab can be used to enhance metrology tools in a fab. The emphasis is on the interaction between a characterization lab and a wafer fab belonging to the same industrial company. Specifically. Description. While single wave ellipsometry has been around for years, spectroscopic ellipsometry is fast becoming the method of choice for measuring the thickness and optical properties of thin films. This book provides the first practical introduction to spectroscopic ellipsometry and the related techniques of reflectometry.

1 May Spectroscopic, specular reflected light measurements (both ellipsometry-SE, and reflectometry-SR) of grating structures have relatively and recently been shown to yield very accurate information on the critical dimensions, wall-angles and detailed wall shape of deep submicron features. The technique is. Spectroscopic Ellipsometry and. Reflectometry from Gratings (Scatterometry) for Critical Dimension Measurement and in situ, Real-Time Process Monitoring. Fred L.

Spectroscopic ellipsometry is a non-destructive, non-contact, and non-invasive optical technique which is based on the change in the polarization state of light as it is . Reflectometry is not sensitive to small changes in thin film thickness, so it is generally used on thicker (> nm) samples, whereas ellipsometry is very. This instrument is a spectroscopic ellipsometer covering the spectral range – nm and using liquid crystals to modulate the polarisation. Reflectometer data were obtained using Surfoptic's own development Imaging Reflectometer ( SIRS75). Measurement time for ellipsometry depended upon sample roughness ( and. Ellipsometry.
