Adhesives Research Inc., a global developer and manufacturer of specialty pressure sensitive adhesive (PSA) technology, has introduced ARclad 8904, a 5-mil double-faced tape with both a permanent and removable adhesive. This tape is used for bonding chemical mechanical planarization (CMP) polishing pads to granite or stainless steel platens used for semiconductor wafer polishing.

The permanent adhesive surface of this tape is designed to bond aggressively to the polishing pad material. It is a high-strength adhesive that will typically generate fiber-tearing bonds when using rotary lamination along with pressure and, when appropriate, heat assistance.
