Ellipsometry Analytical Service

Overview

Ellipsometry is a non-destructive optical technique used to measure the thickness and optical properties (such as refractive index and extinction coefficient) of thin films. It works by analyzing the change in polarization of light reflected off a surface.

Key features of ellipsometry:

• Applications: Commonly used in semiconductor, optics, and materials science to characterize films on substrates.
• High Sensitivity: Can detect sub-nanometer changes in thickness.
• Measurement Parameters: Provides information on film thickness, optical constants, and material uniformity.
• Wide Range: Suitable for single layers, multilayers, and complex stacks.

Ellipsometers are versatile tools for thin-film analysis, offering precise, real-time data for both research and industrial processes.

Project Overview

a. n (Refractive Index) and k (Extinction Coefficient) values.
b. Film Thickness.

The spectral testing range for standard ellipsometers is 370 to 1000 nm. For other ranges, please contact the project manager at 400-831-0631.

The measurable film thickness range is 0.5 nm to 10 µm

Sample Requirement

• Sample Condition: The material is typically in the form of bulk or thin film, with no specific size requirements.

• For Films on Substrates:

  • To measure refractive index and extinction coefficient, the substrate thickness should be as thick as possible.
  • The film thickness should be below 10 µm.
  • For single-layer film samples without a substrate, thicker films are preferred, ideally over 500 µm.
  • The film should be a transparent thin film with a uniform surface, while the substrate does not need to be transparent.

• Special Cases: Please communicate in advance for specific requirements.
