Abstract
A processing tape may include a base layer, an adhesive layer disposed on the base layer, a protection release film on the adhesive layer, and a first release layer interposed between the adhesive layer and the protection release film. The first release layer may include a silicone-based material and may be non-photo-curable.
Claims8
A processing tape, comprising:
- a base layer;
- an adhesive layer disposed on the base layer;
- a protection release film on the adhesive layer;
- and
- a first release layer interposed between the adhesive layer and the protection release film,
