  • Patent number: 11989027
    Abstract: 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.
    Type: Grant

  • Patent number: 7758404
    Abstract: 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.
