Abstract:
A surface treatment apparatus includes a treatment vessel which contains a treatment solution, a transfer device which transfers a substrate through an interior portion of the treatment vessel in an in-plane direction of the substrate, and a jet device which is positioned in the interior portion of the treatment vessel and jets the treatment solution onto a surface of the substrate such that the surface of the substrate is treated with the treatment solution in the interior portion of the treatment vessel. The jet device has a nozzle hole which jets the treatment solution in a jet direction set parallel or diagonal with respect to the substrate surface.
