Abstract: An apparatus for chemically mechanically planarizing a semiconductor wafer is disclosed having a continuous polishing strip with first side having a fixed abrasive surface and a second side opposite the first side. In one embodiment, a first drive roller holds a first end of the polishing strip, a second drive roller holds a second end of the polishing strip, and a pair of support rollers contacts the second side of the polishing strip on either end of a polishing strip support. A drive motor is operably connected to the first and second drive rollers for moving the polishing strip in a linear, bi-directional manner.

Abstract: A method and apparatus for conditioning a polishing pad are described. The method includes steps of providing a chemical mechanical polishing apparatus having a polishing region and a conditioning region; cycling a polishing member through the apparatus; contacting the polishing member in the conditioning region with a conditioning member; and conditioning the polishing member. The apparatus includes an end effector adapted to receive a conditioning member, the end effector being attached to an arm that can be moved horizontally and vertically, and a strain gauge that monitors the force applied to a polishing member.

Abstract: A method and apparatus are disclosed for chemically-mechanically polishing and planarizing semiconductors. An apparatus includes first and second rollers connected by a tension belt. A polishing member is releasably attached to the first and second rollers. A method includes clamping a first portion of a continuous strip of polishing member to a first roller, clamping a second portion of the continuous strip to a second roller, applying a tension to the continuous strip and rotationally reciprocating the rollers while pressing a semiconductor wafer against the continuous strip.
