The NanoSpec 6100 measures the thickness of transparent and semi-transparent thin films and film stacks through non-contact spectroscopic reflectometry. The automated stage and autofocus system enables rapid generation of film thickness uniformity maps.

Announcements

None at this time.

Capabilities

  • Film thicknesses in the range of 200 Å to several µm
Maximum thickness is film dependent.
  • Up to three layers of thin films
  • The NanoSpec measures film thickness using fixed “material file” optical constant values for n and k versus wavelength. If the optical properties of your film differ from the material file, your film thickness measurement may be inaccurate.

System overview

Hardware details

  • Halogen light source in visible wavelength range 400 - 800 nm.
  • Measurement spot size is objective dependent
    • 4x objective → 62.5 µm in diameter
    • 10x objective → 25 µm in diameter
  • Measurement time: typically < 1 sec/site
  • Automated stage for rapid wafer map data collection

Substrate requirements

  • Wafer Size - pieces up to 8" wafers
  • Wafer type - silicon, gallium arsenide, indium phosphide, and other materials available in material file database (Note: thin films on transparent substrates cannot be measured.)
  • Maximum sample thickness - 1.25 mm (4" mounted on 6")

Material restrictions

The NanoSpec 6100 is designated as a General class tool. Below is a list of approved materials for the tool. Approved means the material is allowed in the tool under normal circumstances. If a material is not listed, please create a helpdesk ticket or email info@lnf.umich.edu for any material requests or questions.


  • No liquids or uncured spin on films.
  • No solvents under lenses. Solvents will degrade lens coatings.

Supported processes

  • There are 200 programs and recipes on the NanoSpec as well as many optical constant material files.
  • If the program, recipe, or material file you need are not on the tool, please submit a Helpdesk ticket to contact the tool owner for assistance.
  • The Woollam M-2000 Ellipsometer can be used to measure optical constants for custom films.
