Method for patterning materials on a substrate
A patterning method involves providing a flexible web comprising embedded electrical charges, deposition material having polar properties, a substrate, and a transfer electrode, wherein the flexible web is passed through the deposition material and accumulates material in accordance with the embedded electrical charges, and the accumulated material is transferred to the substrate at the transfer electrode. A production line may be configured in a reel-to-reel implementation. Each station may include finishing operations on the deposited material, including but not limited to heating, annealing, curing, fusing, surface-treating, laser-processing, charge neutralizing, barrier processing, etching, electroplating, and passivating.
