Overview
![Profilometer](http://www.vanderbilt.edu/vinse/wp-content/uploads/sites/40/2024/04/profilometer.png)
The Bruker Dektak 150 uses a diamond-tipped stylus to trace surface topography. Surface roughness and step heights can be easily measured, and the stress analysis upgrade allows one to determine wafer stress due to film deposition.
