Abstract
A method and apparatus for thermally attaching web-based polishing pads in a chemical-mechanical planarization (CMP) system. Specifically, one end of a first web-based polishing pad and an end of a second web-based polishing pad are inserted in a thermal sealing unit. The ends of the polishing pads are brought into contact with each other and secured in place within the thermal sealing unit. A heating element within thermal sealing unit is activated, thereby fusing the polishing pads.
