The Adwill E series of UV curable back grinding tapes ensure against wafer surface damage during back grinding and prevent wafer surface contamination caused by infiltration of grinding fluid and/or debris. Adhesion of the tapes can be substantially decreased with UV irradiation, allowing easy removal without placing stress on the wafer. This feature makes the series suitable for the processing of large diameter, thin wafers.

1.	High device reliability Since contamination of the wafer surface is extremely minimal, the wafer does not require cleaning after back grinding.

2.	Maintains a high level of cleanness throughout the production system The adhesive coating environment exceeds class 100 (US Federal Standard 209b).

1.	Tape for preventing wafer bow after back grinding, and for high-bump wafers The inherent stress relaxation capability of this tape, curtails wafer bow that would otherwise arise after back grinding due to residual stress during tape lamination. Moreover, by dispersing stress during back grinding of high-bump wafers, this tape prevents wafer damage and wafer dimples, while enhancing wafer thickness accuracy.

2.	*Improved wafer thickness accuracy (T.T.V.)** High precision tape thickness accuracy ensures precision wafer thickness after back grinding. * T.T.V.=Total Thickness Variation

1.	Fully protects the wafer surface during back grinding and prevents wafer surface contamination from infiltration of grinding fluid and/or debris.

2.	There is virtually no residual adhesive after tape is peeled off.

3.	For cases in which slight contamination remains because of wafer surface configuration, the lineup includes a type that can be removed by cleaning with pure water. Additionally, there is no danger of contamination from cleaning fluids because there are no water-soluble ingredients of light molecular weight in the adhesive.

4.	High precision tape thickness accuracy ensures precision wafer thickness after back grinding.

1.	A special-purpose tape for removing back grinding tape with the Wafer Mounter RAD-2500 series and the BG Tape Remover RAD-3000 series.

2.	This tape, used in combination with each equipment, allows the removal of back grinding tape without damaging the wafer.

3.	Regardless of the back grinding tape's material, the peeling tape is securely adhered by thermo-compression bonding, allowing the complete removal of the back grinding tape.
