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.

A front end conveyor has an upstream end and a downstream end, a lower deck including a plurality of primary sheet supports and an upper deck including a plurality of sheet guides. Upper portions of the primary sheet supports lie in a first plane and the sheet supports and sheet guides define a sheet transport path for moving sheets in a sheet transport direction. A pivotable sheet support extends from an upstream end of the lower deck and has at least one surface lying in a second plane. The pivotable sheet support is pivotable from a first position in which the second plane forms a first angle with the first plane and a second position in which the second plane forms a second angle with the first plane, the second angle being different than the first angle.

A method and apparatus for cleaning surfaces of an object. A platform may be moved along a path relative to the object using a robotic device. A liquid may be applied onto the plurality of surfaces of the object using an applicator associated with the platform. The liquid may be worked into the plurality of surfaces using a plurality of cleaning elements associated with the platform to dislodge undesired material from the plurality of surfaces. A plurality of flexible members may be moved along the plurality of surfaces to dry the plurality of surfaces and remove the undesired material from the plurality of surfaces. An airflow may be generated that moves the undesired material into a vacuum duct in a vacuum system.
