Abstract:
A processing apparatus comprising:a first nozzle for supplying a treatment liquid for applying a designated process on a substrate; a first liquid passage connected to the first nozzle, for transporting the treatment liquid to the first nozzle; a pressurizing mechanism for pressurizing the treatment liquid thereby to feed it to the first liquid passage; a second nozzle for supplying a charge removing liquid to the substrate; and a second liquid passage arranged independently of the first liquid passage and connected to the second nozzle, for transporting the charge removing liquid to the second nozzle; wherein the second nozzle and the second liquid passage are both made from a material which will not dissolve even though the charge removing liquid dissolves metallic components and the charge removing liquid comes into contact with the second nozzle and the second liquid passage.
