The Zygo NewView 5000 is a non-contact optical 3D profiler. It uses scanning white light interferometry to image and measure the microstructure and topography of surfaces. It provides graphic images and high-resolution numerical analysis to accurately characterize the surface structure of test parts.

The Zygo is typically used for measuring depth of DRIE trench features that are too narrow and/or deep to be measured with the Dektak XT contact profilometer. It is also frequently used for surface roughness analysis.

Announcements

  • Bipolar scans have stopped working. Extended scan is the only scan option that currently works on the tool.
  • Do NOT make adjustments to the 50x objective equal-path ring. The 50x objective is damaged and this adjustment no longer rotates easily. This adjustment is intended to compensate for temperature variation. Since the temperature in the cleanroom is well regulated, no adjustment should be needed. If the scans using the 50x objective are no longer working, please submit a hardware level Helpdesk ticket.

Capabilities

  • Vertical Resolution: 20 nm (Bipolar scans are no longer working which previously provided sub nm vertical resolution)
  • Lateral Resolution Range: 0.64 – 2.6 μm (objective and zoom dependent)
  • Maximum Vertical Step Height: 5 mm
  • Maximum Trench Aspect Ratio: ~10:1

System overview

Hardware details

  • Objectives: 5x, 10x, 50x
  • Image zoom: 0.4x to 2x (secondary zoom)
  • Vertical scan rate: ≤ 10 μm/sec

Substrate requirements

  • Max Sample Thickness: 104 mm
  • Max Roughness: ≤ 100 μm Rp
  • Reflectivity: 4-100%
  • Opaque and transparent surfaces can be analyzed
Transparent materials can complicate set up and cause error in measurements if there is a higher reflectivity underlying material or substrate.
If your sample has surfaces with dissimilar materials, the accuracy of step height measurements may be degraded. Dissimilar optical properties cause relative phase shift error in the measured vertical height between the surfaces.

Material restrictions

The Zygo NewView 5000 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 solvents under objective lenses! Solvents and solvent fumes will degrade lens coatings.
  • As a General Class tool, there are no specific material restrictions for this equipment
