Abstract:
An apparatus for processing a substrate comprising:a substrate holding mechanism configured to hold the substrate substantially horizontally; a chemical solution discharge/suction mechanism having a chemical solution discharge/suction portion which has a chemical solution discharge nozzle for discharging a chemical solution from a chemical solution outlet opposed to the substrate, two chemical solution suction nozzles connected to two chemical solution inlets which are arranged on the same plane with the chemical solution outlet and arranged to sandwich the chemical solution outlet, said two chemical solution suction nozzles sucking a chemical solution on the substrate from the chemical solution inlets, and members each arranged between the chemical solution discharge nozzle and each of the two chemical solution suction nozzles, the bottom surface of said members being provided on the same plane with the chemical solution outlet and the two chemical solution inlets; a chemical solution supply/suction system configured to supply the chemical solution to said chemical solution discharge/suction mechanism simultaneously with sucking the chemical solution by the chemical solution supply/suction mechanism; and a moving mechanism configured to horizontally move the chemical solution discharge/suction portion relative to the substrate in a direction along which said two chemical solution inlets and said chemical solution outlet are arranged.
