Precision Cleaning Service

We realized an extremely environment-friendly cleaning method.
We receive orders and take care of everything up to the shipping.

Semiconductor and FPD production processing is progressing every single day and the needs for better quality grow constantly. Our Dry Ice System has received a patent for its originality patent No.3030287

In addition to cleaning by dry ice blast (CO2), we are able to apply precision cleaning by sandblasting, chemical solution, calcination, DI water etc. depend on type of contamination. Also detoxifying treatment of toxic material is available.

From receiving the parts for delivery up to shipping

  • Estimate
    Usage process (Ion Implant,sputter, CVD,etching,etc)
    Name of machine
    Way of blasting (gas)
    The more information we are given, the better estimate we can make If we do not have experience with the certain material, we start from test cleaning and prepare the most suitable cleaning recipe.
  • Delivery date : Around 1 week

No.1 : Cleaning parts with thin holes

No.2 : Initial cleaningClose Up!

Initial Cleaning method
  • We clean the surface of the new parts and we reduce the particles, which appear during the beginning of the change of parts.
  • In the sub-micron generation, in order to achieve low number of particles, initial cleaning is demanded!
