Apparatus for an inert anode plating cell

In one example, an electroplating apparatus is provided for electroplating a wafer. The electroplating apparatus comprises a wafer holder for holding a wafer during an electroplating operation and a plating cell configured to contain an electrolyte during the electroplating operation. An anode chamber is disposed within the plating cell, and a charge plate is disposed within the anode chamber. An anode is positioned above the charge plate within the anode chamber. In some examples, the anode chamber is a membrane-less anode chamber.

Electroplating device and electroplating method

An electroplating device and an electroplating method, the electroplating device includes an electroplating unit for electroplating a production panel. The electroplating unit includes an electrolyte channel for jetting an electrolyte toward the production panel, and an electroplating assembly disposed on an outer surface of the electrolyte channel. The electroplating assembly includes an anode disposed on the outer surface of the electrolyte channel, and a suction channel in the anode which is used for absorbing the electrolyte in a direction opposite to a jet-plating direction. The electrolyte may be uniformly distributed on the production panel by the combination of the electrolyte channel and the electroplating assembly.

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.

Cross flow conduit for foaming prevention in high convection plating cells

The embodiments herein relate to apparatuses and methods for electroplating one or more materials onto a substrate. Embodiments herein utilize a cross flow conduit in the electroplating cell to divert flow of fluid from a region between a substrate and a channeled ionically resistive plate positioned near the substrate down to a level lower than level of fluid in a fluid containment unit for collecting overflow fluid from the plating system for recirculation. The cross flow conduit can include channels cut into components of the plating cell to allow diverted flow, or can include an attachable diversion device mountable to an existing plating cell to divert flow downwards to the fluid containment unit. Embodiments also include a flow restrictor which may be a plate or a pressure relief valve for modulating flow of fluid in the cross flow conduit during plating.
