About This Webinar
Spectroscopic ellipsometry is a nondestructive technique that uses polarized light to probe a sample. In this webinar, presenter Andrew Martin of J.A. Woollam will cover the science behind ellipsometry and the types of information you can extract from the data. You will learn:
  • The fundamental principles of ellipsometry that lead to highly accurate measurements of coating thickness and optical properties.
  • How ellipsometry measurements compare to other characterization techniques.
  • An overview of common applications including high/low stacks, ALD deposition monitoring, temperature-based studies, and more.
