Polishing system, carrier head assembly, and method of polishing a substrate

A polishing system is provided, including a carrier with an offset distance. The offset distance allows a shifted carrier head to cover more surface area of the polishing surface. The offset distance effectively provides an additional rotation of the carrier head about the axis, which allows for a g...

Zusammenfassung:	A polishing system is provided, including a carrier with an offset distance. The offset distance allows a shifted carrier head to cover more surface area of the polishing surface. The offset distance effectively provides an additional rotation of the carrier head about the axis, which allows for a greater area traversed on the polishing surface, improving chemical mechanical polishing uniformity on the substrate.
