Product Description
3M™ Wafer De-Taping Tape 3305 is a transparent polyester film with an adhesive specifically designed for the removal
of the 3M™ Wafer Support Systems (WSS) adhesive from the surface of the device wafer after the carrier glass is
separated from the silicon wafer.
Features and Benefits
• Enables simple, low-stress, room temperature peeling of 3M™ Adhesives from thinned silicon wafers after glass
carrier debonding
• Transparency allows for inspection without tape removal
• High instant adhesion to substrate
• Good holding power
