SEMI-KLEEN and EM-KLEEN series remote plasma cleaners were based on the high efficiency inductively coupled plasma (ICP) discharge technology developed at the Lawrence Berkeley National Laboratory. Our patent pending Turbo Discharge™ technology further improves the plasma strength by as much as 3X compared with traditional ICP discharge technology.

Typical applications:

  • In-situ sample cleaning for FE-SEM, FIB and TEM
  • Contamination removal for semiconductor equipment, such as CD-SEM, EBR, EBI, EUVL
  • High vacuum chamber cleaning to remove water, hydrocarbon and fluorocarbon contamination, reduce the pump-down time
  • Sample cleaning for XPS, SIMS, AES
  • Sample cleaning for ALD after organic solvent cleaning

SmartClean™ technology developed by PIE Scientific combines the most advanced plasma discharge technology in nuclear research and semiconductor industry. EM-KLEEN and Semi-KLEEN plasma cleaners are far more advanced than previous generations of plasma cleaner. Our plasma cleaner can beat competitors on any specification. In addition, many unique features are only available on our products.

Plasma cleaning improves image contrast, reduce charging instability


SEMI-KLEEN and EM-KLEEN series plasma cleaner provides a gentle plasma cleaning solution for contamination control in high vacuum systems, such as SEM, FIB, AES, XPS, ALD, EUVL, etc. It consists of a controller and a remote plasma source. Remote plasma source should be installed on the vacuum chamber to be cleaned. Controller provides the RF power to the remote plasma source. It breaks down the process gas such as oxygen, hydrogen or other gas mixtures and generates reactive radicals. Radical species will then diffuse into the chamber to be cleaned and react with the contaminants. The byproducts are usually low molecule weight, high vapor pressure molecules that can be easily pumped away. Remote plasma cleaner can clean vacuum systems and samples at the same time. Option to support aggressive and sometimes corrosive plasma such as H2, NF3, CF4, NH3 is available.

EM-KLEEN plasma cleaner provides an affordable contamination removal solution for SEM, FIB, XPS systems. SEMI-KLEEN remote plasma source is designed to meet the tough requirement from semiconductor industry. SEMI-KLEEN plasma cleaner has the upgrade option to eliminate nanometer scale particle generation----a feature that is critical for semiconductor capital equipment. Automatic impedance matching option is only available for SEMI-KLEEN Series plasma cleaner. SEMI-KLEEN plasma cleaner is very versatile. It can be configured to include sapphire tube option for aggressive process gases such as H2, NF3, CF4 and NH3. We also provide custom design service based on SEMI-KLEEN plasma cleaner to meet specific application requirements. For example, SEMI-KLEEN plasma cleaner can be used for etching and deposition on ALD systems.
