Silicon Wafer Reclaim

Ask us to remove the membranes which other companies couldn't.

  • We don’t use the chemicals, but use our own developed plasma etching machine.
  • At this method the decreased portion of the wafer is very thin (about 1μm).
    Due to this effective reclaiming method it becomes possible to lower the cost.
  • Since no use of the special chemicals the damage to the wafer is very limited and possible to minimize the burden to the environment.
  • We are developing/selling the plasma etching machine. Please feel free to ask us anything.
  • ※We are also reclaiming the 300mm wafer.
