摘要:
The present invention provides a polishing platen which does not require a large force for removing a polishing pad from an upper surface of the polishing platen and can thus make it relatively easy to remove the polishing pad therefrom. The present invention also provides a polishing apparatus having such polishing platen. The polishing platen (12) according to the present invention includes a surface to which a polishing pad is attached. The surface of the polishing platen (12) includes a combination of a first surface (20) and a second surface (21) having a surface roughness which is different from that of the first surface (20).

A wafer transferring apparatus includes a top ring for holding a wafer on a lower end surface thereof and a pusher mechanism for transferring the wafer to and from the top ring. The pusher mechanism has a wafer rest for placing the wafer thereon and is arranged to allow the wafer released from the lower end surface of the top ring to be seated on the wafer rest. The pusher mechanism also has a sensor mechanism for detecting when the wafer is properly seated on the wafer rest. The sensor mechanism is adapted to block sensor light emitted from a light-emitting device by the wafer seated on the wafer rest.

A wafer transferring apparatus includes a top ring (60) for holding a wafer (W) on a lower end surface thereof and a pusher mechanism (10) for transferring the wafer (W) to and from the top ring (60). The pusher mechanism (10) has a wafer rest (40a) for placing the wafer (W) thereon and is arranged to allow the wafer (W) released from the lower end surface of the top ring (60) to be seated on the wafer rest (40a). The pusher mechanism (10) also has a sensor mechanism (50) for detecting when the wafer (W) is properly seated on the wafer rest (40a). The sensor mechanism (50) is adapted to block sensor light emitted from a light-emitting device (51) by the wafer (W) seated on the wafer rest (40a).
摘要:
The present invention relates to a substrate processing apparatus which can improve a tact time of substrate processing. A polishing apparatus as the substrate processing apparatus includes plural polishing sections (3a, 3b) each for polishing a semiconductor wafer (W), and a swing transporter (7) for transferring the wafer (W). The swing transporter (7) includes a wafer clamp mechanism (112) adapted to clamp the wafer (W), a vertically moving mechanism (104, 106) for vertically moving the wafer clamp mechanism (112) along a frame (102) of a casing of the polishing section (3a), and a swing mechanism (108, 110) for swinging the wafer clamp mechanism (112) about a shaft adjacent to the frame (102).

A polishing apparatus comprises a polishing table having a polishing surface thereon, a top ring for pressing a workpiece to be polished against the polishing surface, and a dresser for dressing the polishing surface on the polishing table. The dresser comprises a dressing element provided on a surface of the dresser for dressing the polishing surface by sliding contact with the polishing surface, and an ejection nozzle provided on the surface of the dresser for ejecting a fluid supplied from a fluid source toward the polishing surface.
