An adhesive chosen specifically for semiconductor CMP
3M™ Double Coated Polyester Tape 442KW features 3M™ Adhesive 830, a firm rubber adhesive system that combines adhesion, temperature performance and solvent resistance and provides a quick stick to a wide variety of materials. This adhesive has been chosen specifically for use in semiconductor CMP applications, as it laminates easily to polishing pads. It also removes cleanly from many surfaces, excellent for use with semiconductor platen.
