Patent ID: 7052367

Claim:
A polishing apparatus for polishing a work surface having protrusions and depressions thereon with slurry containing particles, comprising: a moving stage on which the work surface is mounted; a processing circuit that generates coordinate values of the work surface by associating work surface measurements with coordinates of the moving stage; an operational control unit that stores the generated coordinate values; a stage control circuit that adjusts the position of the moving stage based on the coordinate values stored in the operational control unit; a laser optical system that scans the work surface by selectively projecting and irradiating laser light onto the work surface; and a polishing tool system that applies pressure to the work surface in an axial direction and provides rotational movement, wherein the stage control circuit adjusts the position of the moving stage as the laser optical system scans laser light onto the depressions of the work surface, so that the polishing particles of the slurry are aggregated in the depressions.
