The present invention is directed to a plating apparatus and method in which bubbles generated at the plating surfaces are easily removed and the uniformity of the thickness of the plated film within the plated surface can be improved. The plating apparatus comprises a cassette table for loading a cassette in which a substrate having a plating surface is contained. An aligner for aligning the substrate, a rinser-dryer for rinsing and drying the substrate, and a plating unit for plating the substrate are also provided. The plating unit comprises a plating vessel containing a plating solution, a holder for holding the substrate to immerse the substrate in the plating solution in the plating vessel. The plating surface is exposed to a nozzle which ejects the plating solution toward the plating surface.
