Abstract:
1. A substrate treating apparatus comprising: a substrate support portion which supports and fixes a substrate; a nozzle including a first discharge region, a second discharge region, and a first jet region disposed between the first discharge region and the second discharge region, the first discharge region configured to discharge a first solution to the substrate, the second discharge region configured to discharge a second solution to the substrate and the first jet region configured to spout a first gas to the substrate; and a moving portion configured to relatively move the nozzle with respect to the substrate in a direction substantially parallel to a main surface of the substrate, wherein a width of the nozzle taken in a direction perpendicular to a relative movement direction of the first discharge region and first jet region is equal to or more than a maximum diameter or longest side of the substrate, and wherein a plurality of openings are formed in the first and second discharge regions and a rectangular opening is formed in the first jet region, and a total width of the first and second discharge regions and the first jet region, taken in a direction substantially parallel to the relative movement direction, is smaller than a diameter of the substrate.
