ABSTRACT:
The present invention is a high-speed planarizing machine with a platform that holds the upward facing wafer stationary during planarization, and a carrier positioned opposite the platform. The carrier rotates about an eccentric axis and translates in a plane that is substantially parallel to the wafer. A polishing pad is smaller in diameter than the wafer and is attached to the carrier and positioned opposite the wafer. The carrier rotates and translates the polishing pad across the wafer while the wafer is held stationary.
