Thickness measurer
There are 2 thickness measurers in the cleanroom, both positioned in cleanroom D-3. The Thickness measurer is for measuring all sorts of samples. The thickness measurer (wafers) is solely for measuring the thickness of wafers or depths of grooves on wafers.
During a KOH etch it can be helpful to ensure no over-etching by making a thickness measurement during the etching.
The user manual, technical information and contact information can be found in LabManager:

Quality Control (QC) for the Thickness measurer |
The measured standard thickness is 0.1 mm. The measured result has to be within ± 0.005 mm. The QC is preformed once a year. |
