Contamination removal solution for semiconductor capital equipment

SEMI-KLEEN remote plasma cleaner is designed to meet the tough requirements from semiconductor industry. It can be used on electron beam review system (EBR), electron beam inspection system (EBI), CD-SEM, electron beam lithography system, EUV lithography (EUVL) and EUV mask inspectors. Besides all the standard hardware features on EM-KLEEN plasma cleaners, such as pressure sensor, automatic gas flow controller, plasma strength sensor, temperature sensor, cooling fan and LCD touchscreen controller, SEMI-KLEEN plasma cleaner also integrates the latest plasma source design technologies from semiconductor industry to reduce particle generation risk. Low particulate design on SEMI-KLEEN plasma cleaner has been qualified by semiconductor capital equipment manufacturers and it outperforms competition by multiple orders of magnitude. Standard SEMI-KLEEN plasma cleaner uses high purity quartz tube with external antennas. It can be used to generate air, O2, Ar+O2, H2 and Ar+H2 plasma at low pressure. Proprietary antenna design reduces plasma potential, thus reducing ion sputtering on the source chamber. In addition, chamber materials have been carefully selected to withstand plasma etching. Combined with proprietary dual stage particle filtering technology, SEMI-KLEEN plasma cleaner can meet the toughest PWP requirement from customers like Intel, Samsung and TSMC.

Feature list:

  • Dual stage particle filtering technology that can remove almost all the particles larger than 3nm.
  • Low particulate high reliability plasma source design technology for semiconductor industry.
  • Option to support automatic RF impedance matching.
  • Instant plasma ignition at extremely low pressure. User never needs to worry about whether plasma ignites or not.
  • Electronic gas flow control with pressure sensor feedback control. User can directly specify different source operating pressure. Plasma cleaner will maintain the set pressure by automatically adjusting gas flow through a servo feedback control loop provided by the pressure sensor.
  • Plasma probe monitors the plasma strength to guide user setup optimal recipe. Optimal gas flow can vary with different system pumping speed and chamber size. Our plasma cleaner gives user the freedom to change gas flow electronically and optimize the source pressure based on the feedback from the plasma strength probe.
  • Microcomputer with touchscreen user interface.
  • Intuitive remote PC control user interface through RS232/RS485 protocol.
  • Customizable SmartScheule function on the microcomputer can take care of your system autonomously.
  • Support 60 customizable recipes.
  • Active fan cooling for high power high speed cleaning
  • Overtemperature interlock protection.
