KLA-Tencor Surfscan 6420

The image is from the cleanroom at the place it was refurbish in California.

Particles counting of a unpatterned surface. A broad range of particles size from 0.1 µm to greater than 3 µm can be measured on a polished silicon or epitaxial layers. Thin films as e.g. Poly-si, Nitride and thermal Oxide can also be inspected. The system will remove small surface roughness so it not count as a particle.


The user manual(s), quality control procedure(s) and results, user APV(s), technical information and contact information can be found in LabManager:
