An electrochemical-deposition apparatus includes an electrode array, a photoconductor, an electrically conductive layer, an electromagnetic-radiation emitter, an electric-power source, and a controller. The controller is configured to direct electric power to be supplied from the electric-power source to the electrically conductive layer and direct the electromagnetic-radiation emitter to generate electromagnetic radiation. When the electric power is supplied to the electrically conductive layer and when the electromagnetic radiation is generated, the photoconductor is illuminated at a first radiation level and a first level of electric current is enabled through the photoconductor and the at least one deposition electrode. When the electric power is supplied to the electrically conductive layer and when the electromagnetic radiation is generated, the photoconductor is illuminated at a second radiation level and a second level of electric current is enabled through the photoconductor and the at least one deposition electrode.

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.

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.
