Assemblies and methods for anodizing a workpiece selectively using a combination of a mechanical mask and a gas bubble or air pocket mask
Metal components that require anodic coating or anodizing, may also require some surfaces of the component to be free of the anodic coating for the purpose of conductivity. The presence of the anodic coating on surfaces of the component that require conductivity would make those surface more electrically resistant or nonconductive. A combination of a gas pocket or air bubble to create a barrier to anodizing in a cavities of a workpiece (or in a cavity created by a conformal compression material) and the use of a (e.g., compressible) mask/seal material to mask off other surfaces though a gasket sealing function, is used. The mask/seal material may be compressed and makes a seal of some surfaces using pressure from clamping or pressure mechanisms. At least two opposing surfaces are masked by the compressive mask/seal material on one end and a gas pocket on the other end. The gas pocket will allow the anode to make firm electrical contact with the workpiece. The unmasked surfaces of the workpiece will be contacted by the electrolyte and consequently anodized. These anodized surfaces will have more electrical resistance (e.g., have higher resistance, and might even be non-conductive) than the masked surfaces that were not anodized. Further, the selectively anodized surfaces can be colored, seal, or have other conventional post anodizing processes applied.

PLATING APPARATUS, PRE-WET PROCESS METHOD, AND CLEANING PROCESS METHOD
Provided is a technique that allows ensuring a downsized plating apparatus.
A plating apparatus includes a discharge module 50. The discharge module includes a module main body 51 including a plurality of nozzles 52 configured to discharge a process liquid upward, and a moving mechanism 60 including a rotation shaft 61 disposed at a side of a plating tank and connected to the module main body. The moving mechanism 60 moves the module main body by rotation of the rotation shaft. The moving mechanism moves the module main body between the first position and the second position. The plurality of nozzles are arranged such that the process liquid discharged from the plurality of nozzles is brought in contact with a lower surface of a substrate from a center portion to an outer peripheral edge portion when the module main body moves to the second position. The module main body further includes a recovery member configured to recover the process liquid dropped after being discharged from the plurality of nozzles and brought in contact with the lower surface of the substrate.

PLATING APPARATUS AND PLATING PROCESS METHOD
A plating apparatus 1000 includes a plating tank 10 and a substrate holder 30. The plating tank includes an anode 11 arranged in an anode chamber 13. The substrate holder is arranged above the anode chamber and configured to hold a substrate Wf as a cathode. The anode has a cylindrical shape extending in a vertical direction. The plating apparatus further includes a gas accumulation portion 60 and a discharge mechanism 70. The gas accumulation portion is disposed in the anode chamber so as to have a space between the anode and the gas accumulation portion. The gas accumulation portion covers an upper end, an outer peripheral surface, and an inner peripheral surface of the anode to accumulate a process gas generated from the anode. The discharge mechanism is configured to discharge the process gas accumulated in the gas accumulation portion to outside of the plating tank.

METHOD FOR A CHEMICAL AND/OR ELECTROLYTIC SURFACE TREATMENT OF A SUBSTRATE IN A PROCESS STATION
The invention relates to a method for a chemical and/or electrolytic surface treatment of a substrate in a process station and a process station for a chemical and/or electrolytic surface treatment of a substrate.
The method for a chemical and/or electrolytic surface treatment comprises the following steps, not necessarily in this order: mounting a substrate to be treated to a rotor unit, moving the rotor unit with the substrate into a pre-wetting chamber of the process station, applying a pre-wetting fluid to the substrate in the pre-wetting chamber, moving the rotor unit with the substrate at least partially out of the pre-wetting chamber, spinning the rotor unit with the substrate in a spinning plane to centrifugally reduce the pre-wetting fluid at a surface of the substrate, rotating the rotor unit with the substrate normal to the spinning plane so that the substrate faces away from the pre-wetting chamber, moving the rotor unit with the substrate into an electroplating chamber of the process station, applying an electrolyte liquid and an electric current to the substrate for an electroplating process on the substrate in the electroplating chamber, and moving the rotor unit with the substrate at least partially out of the electroplating chamber.
