Polisher (CMP)

The Logitech Orbis Polisher (CMP) is for polishing wafers (removing material in the nm range) it is not for thinning down wafers or other substrates. After CMP it is recommended to use the Post CMP Cleaner to clean the sample for slurry residues left by the CMP.

The user manual, user APV, technical information and contact information can be found in LabManager:
