Wafer grinding, ultra thin, TAIKO - dicing-grinding service

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.

Ring cutter and remover for TAIKO wafers

Wafer with a thickness of less than 80 micron are stabilized for grinding with a ring on the outer perimeter. Before dicing it is necessary to remove the TAIKO ring. Using this method lowers the risks of thin wafer handling (breakage, edge chipping) and decreases warpage. Prior to final processing, wafers must be separated from the ring.
