Decontamination

Decontamination cleans are used to remove trace metals and particles from substrates. This step is required for post processing of wafers and pieces that have gone through KOH-etching, chemical-mechanical polishing (cmp), and the wafer saw. For more about the contamination categories, please visit the Cleanliness (previously Contamination) Groups page.
