Abstract
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.
