A polishing apparatus includes an arrangement of a plurality of units to deal with various operations and a robot having at least one arm. The plurality of units are disposed around the robot and include a loading unit for receiving thereon a, e.g. dry, workpiece to be polished, a polishing system including at least one polishing unit for polishing the workpiece, a washing system and a drying system at least including one washing unit for washing and drying the polished workpiece, and an unloading unit for receiving thereon a resultant clean and dry polished workpiece.

Method and apparatus for dry-in, dry-out polishing and washing of a semiconductor device

To planarize an insulating film formed on a semiconductor substrate, a polishing slurry containing cerium oxide is used to polish the surface of the insulating film. Using the cerium oxide included slurry as a polishing agent, the insulating film is not contaminated by alkali metals during the polishing process. Furthermore, the insulating film is polished at an enhanced polishing rate.

A film formed on a wafer is polished in a CMP unit. Thereafter, the wafer, which is adhered to a wafer holder, is moved to a portion above an optical sensor. A surface of the wafer is radiated with, for example, a visible ray, thereby measuring a thickness of the film which has been polished. A control unit automatically sets a polishing time for polishing a film on a wafer to be polished next.

A polishing apparatus for polishing a surface of a workpiece such as a semiconductor wafer is installed in a clean room. The polishing apparatus includes a polishing section having a turntable with an abrasive cloth mounted on an upper surface thereof, a top ring for supporting the workpiece to be polished and pressing the workpiece against the abrasive cloth, a loading section for loading the workpiece to be polished onto the top ring, and an unloading section for unloading the workpiece which has been polished from the top ring. A cover covers an entire area of movement of the top ring including the polishing section, the loading section and the unloading section. An exhaust duct discharges air of an interior space of the cover to an outside of an installation space of the polishing apparatus.

To planarize an insulating film formed on a semiconductor substrate, a polishing slurry containing cerium oxide is used to polish the surface of the insulating film. Using the cerium oxide included slurry as a polishing agent, the insulating film is not contaminated by alkali metal is during the polishing process. Furthermore, the insulating film is polished at an enhanced polishing rate.
