Cleaning Technology

About us

The group of cleaning technology was established in 1990. We have been dealing with versatile problems related to contamination control in manufacturing processes of semiconductors, LCD, and pharmaceutical products. We will expand the targets of contamination control into the fields of precision machines and foods as well as cleaning technologies for home appliances.

Present status and Prospect in Clean Technology

  1. Control technology and measurement methods for submicron particles (Improvement of filter efficiency, sealing of HEPA/ULPA filter, and containment of emission source)
  2. Survey on the necessity of HEPA filters for indoor ventilation to remove PM 2.5 particles
  3. Control of clean room environment (control of air flow distribution, simulation technology and design of ceiling-less clean room)
  4. On-line and off-line measurement of sub-micron particles and chemical species
  5. Establishment of mini-environment and clean system in semiconductor industries (Simple and economical measurement technologies for nanoparticles in the mini-environment dealing with 300 mm wafer and FOUP, and prevention of electrostatics)
  6. Microbial contamination control technology (cGMP, PIC/S, HACCP and in situ measurement of microbiology)
  7. Risk management for the pioneering industries in clean technology
  8. Clean technology of large size flat panel displays and organic electroluminescence including the prevention of electrostatics
  9. Development of environmentally friendly technologies for energy saving and reduction of CO2
  10. Clean technology for quality control and safety for GMP validation and HACCP in the pharmaceutical and food industries
  11. Clean equipment, sterilization and hazard management for processes of manufacturing biologically active agents and culture process in regenerative medicine
  12. Revision and development of ISO documents in ISO/TC209 and TC142 for clean room and air filters
  13. Access of submicron size oil mist contaminations in workspaces generated from cutting machines
