Appl. No.:

10/942600

International Classification:

B24B 57/02
B24B 7/22

US Classification:

451 41, 451 60, 451446

Abstract:

A substrate polishing apparatus and method are described. A base includes at least one movable platen to engage a polishing pad. At least one carrier head assembly presses a substrate against the polishing pad substantially within a polishing area during a polishing operation. A polishing solution dispenser applies a polishing solution to the polishing pad substantially within the polishing area during the polishing operation. A polishing solution retaining mechanism is attached to one of the base or the carrier head assembly. The retaining mechanism engages a top surface of the polishing pad and retains the polishing solution substantially within the polishing area during the polishing operation. Some implementations may reduce polishing solution consumption and allow for increased angular velocity.

International Classification:

C03B 20/00

US Classification:

65 2912, 65158

Abstract:

The present disclosure relates to methods for automated inspection of the orientation of a glass substrate () having a side that is coated and/or impregnated with a non-glass material (e.g., tin). One method () includes: picking up the glass substrate () by using an automatic lifting assembly (); inspecting a side of the glass substrate () with a sensor () so as to determine whether the inspected side is coated or impregnated with the non-glass material; determining whether the glass substrate () is correctly oriented based upon the inspection results; and using the automated lifting assembly () to place the glass substrate () on a conveyor () in response to determining that the glass substrate () is correctly oriented.
