Use of steam for pre-heating of CMP components

A method of temperature control for a chemical mechanical polishing system includes directing a gas that includes steam from an orifice onto the component in the polishing system while the component is spaced away from a polishing pad of the polishing system to raise a temperature of the component to an elevated temperature, and before the component returns to an ambient temperature, moving the component into contact with the polishing pad.

Bevel edge removal methods, tools, and systems

A tool and methods of removing films from bevel regions of wafers are disclosed. The bevel film removal tool includes an inner motor nested within an outer motor and a bevel brush secured to the outer motor. The bevel brush is adjustable radially outward to allow the wafer to be inserted in the bevel brush and to be secured to the inner motor. The bevel brush is adjustable radially inward to engage one or more sections of the bevel brush and to bring the bevel brush in contact with a bevel region of the wafer. Once engaged, a solution may be dispensed at the engaged sections of the bevel brush and the inner motor and the outer motor may be rotated such that the bevel brush is rotated against the wafer such that the bevel films of the wafer are both chemically and mechanically removed.
