In some examples, a dual-mode autonomous guided vehicle (AGV) is provided for docking a module in a fabrication bay. An example AGV may comprise a chassis for supporting the module on the AGV; drive means to transport the AGV under autonomous guidance, in a module transportation mode, to a specified location within the fabrication bay; a Cartesian x-y movement table to move the module under autonomous guidance, in a module docking mode, in an x- or y-docking direction, into a specific docking position; and a z-direction lift mechanism to move the module in a z-docking direction during the module docking mode.

A collar may be provided having an aperture through it through which the turret of a wafer handling robot may be extended or retracted. The collar may have one or more radial gas passages. Gas directed inwards towards the turret from the radial passage(s) may turn downward when it strikes the turret. A bellows may be optionally affixed to the bottom of the turret and to the bottom of the base such that the volume of the base occupied by the turret and the bellows remains generally fixed regardless of the degree to which the turret is extended from the base.

An apparatus, system and method for cleaning a substrate edge include a composite applicator that cleans bevel polymers deposited on wafer edges using frictional contact in the presence of fluids. The composite applicator includes a support material and a plurality of abrasive particles distributed within and throughout the support material. The composite applicator cleans the edge of the wafer by allowing frictional contact of the plurality of abrasive particles with the edge of the wafer in the presence of fluids, such as liquid chemicals, to cut, rip and tear the bevel polymer from the edge of the wafer.
