Abstract:
A polishing method for a rotating polishing tool formed by an elastic member having a polishing surface along a plane perpendicular to a rotary shaft, pressing the polishing surface to a surface to be polished of an object to be polished held on a holding table, and relatively moving the object to be polished and the polishing tool along a holding surface of the holding table, to polish the surface of the object to be polished, said method comprising the steps of:inclining the rotary shaft of the polishing-tool by a predetermined angle relative to a direction perpendicular to the holding surface of the holding table and toward a direction of advance of the movement of the polishing tool, and inclining the shaft of the polishing tool relative to the direction perpendicular to the holding surface of the holding table and in a direction corresponding to a rotational movement of a leading portion of the polishing tool with respect to the direction of advance for reducing elastic deformation of the polishing surface in a region where the polishing surface rides up on an edge of the surface of the object.
