Wafer grinding, ultra thin, TAIKO

Taiko Grinding. TAIKO is a DISCO developed wafer back grinding method. By enabling an outer support ring to the wafer (the TAIKO ring, Japanese for drum), back grinding is performed on the inner circular area of the wafer, while leaving an edge of a few millimeters unprocessed. Taiko simplifies thin wafer handling and lowers warpage.
