<p>A polishing apparatus has a polishing table having a polishing surface, a carrier for carrying a plate-like member and bringing the plate-like member into contact with the polishing surface, and a dresser including a dressing tool adapted to be brought into contact with the polishing surface to dress or normalize the polishing surface. The carrier is movable along a first path between a work position for bringing into contact the plate-like member with the polishing surface and a rest position. The dresser is movable along a second path between a work position for bringing the dressing tool into contact with the polishing surface and a rest position. The first and second paths have a common overlapping area. A contact prevention device is provided to prevent the carrier and the dresser from coming into contact with each other. An actuator is provided to bring the plate-like member into a condition that a predetermined area of the surface of the plate-like member extends beyond a peripheral edge of the polishing surface.</p> |
