Abstract:
The purpose of the present invention is to reduce a burden of an exhaust system which absorbs a cup body and to prevent effectively a processing liquid from being attached to a substrate after the processing liquid supplied to the substrate is scattered from the substrate. When a substrate (W) is processed, a protective wall (52) of a ring shape is located on the substrate which is maintained on a substrate maintaining unit (3). The protective wall (52) of the ring shape is extended along a circumference direction of the substrate. A radius direction position of a circumference edge unit of the protective wall lower side is same as a radius direction position of an inner circumference edge of the circumference edge unit of the upper side of the substrate which is maintained on the substrate maintaining unit or is located on the outside of the radius direction. A first air gap (G1) is formed between the protective wall and the upper side of the substrate. A second air gap (G2) is formed between the protective wall and a wall body (262) which defines an upper opening of the cup body. Gas located in the upper side of the substrate is inserted into an internal space of the cup body through the first and second air gaps if the internal space of the cup body (2) is absorbed.
Abstract:
The present invention is to effectively suppress a processing liquid supplied to a substrate from being scattered and adhered again onto the substrate, while reducing a load on an exhaust apparatus that exhaust a cup. When a substrate W is processed, a ring-shaped cover member (5) covers a peripheral portion of the upper surface of the substrate (W) held by the substrate holding unit (3), and a central portion of the substrate located at an inner position than the peripheral portion in a radial direction is exposed without being covered by the cover member. The bottom surface (52) of the cover member forms a gap (G) between the lower surface of the cover member and the peripheral portion of the substrate held by the substrate holding member. When the interior surface of the cup (2) is exhausted through an exhaust pipe (245), a gas present above the cover member is introduced into the interior space of the cup through a space enclosed by the internal peripheral surface (51) and the gap (G).
