When a device wafer is chucked and is rotated about an axis thereof, arc-shaped work faces of first and second inclined-face-polishing members are brought into line-contact with inclined faces disposed at front and rear faces, respectively, of the device wafer, the arc-shaped work face of a peripheral-face-polishing member is brought into line-contact with a peripheral face of the device wafer, and a disc-shaped work face of a peripheral-edge-polishing member is brought into planar contact with the front face of the device wafer at a peripheral edge thereof, whereby the inclined faces, the peripheral face, and the peripheral edge are polished simultaneously by the respective polishing members. Thus, an unnecessary part of a metallic film is removed from the periphery of the device wafer.
