Wafer Reclaim / Recycling

Wafer recycling is a combination of wet chemical and dry etching to remove most deposited semiconductor thin films. To remove scratches, scribe marks, silicon haze or other related defects, polishing will be done.

Many companies have taken advantage of our recycling service. We have successfully processed and recovered for re-use prime and test wafers of all sizes including 300mm.
