Sample Overview

  • ● Sample: Si₃N₄ on Si or dielectric stack
  • ● Typical thickness: Application-dependent thin-film range
  • ● Method: Reflectance-based thickness measurement, subject to sample condition and optical contrast.

Measurement Considerations

Model selection depends on the film stack, substrate, target thickness range, surface condition, and optical contrast.
