> [Technical report] Recent progress on the measurement methodology of surface roughness inside the PFA tubes

We assume that in order to discuss the possibility of residence of nano-sized particles on the inner surface of PFA tubes for semiconductor manufacturing equipment, the method for measuring the surface roughness inside the tubes must be newly invented. This report makes a proposal for a method to measure surface roughness at the nano-level and demonstrate the necessity for this measurement.
