Abstract:
A substrate processing apparatus comprising:a substrate holding element horizontally holding a substrate in a stationary state; a developer supplying moving element including a developer discharge port having a discharge width at least equivalent to the diameter of said substrate for moving from a developer supply start position on a first end of said substrate held by said substrate holding element to a developer supply end position on a second end and supplying a developer to the surface of said substrate; and a rinse supplying moving element including a rinse discharge port having a discharge width at least equivalent to the diameter of said substrate for moving from said developer supply start position to said developer supply end position after said developer supplying moving element supplies said developer to the overall surface of said substrate for supplying a rinse to the overall surface of said substrate from said rinse discharge port, wherein, said rinse supplying moving element has a rinse suction port having a suction width at least equivalent to the diameter of said substrate at the back of said rinse discharge port in the direction of movement of said rinse supplying moving element so that said rinse supplying moving element moves from said developer supply start position to said developer supply end position after said developer supplying moving element supplies said developer to the overall surface of said substrate for supplying said rinse to the overall surface of said substrate from said rinse discharge port while recovering said supplied rinse from said rinse suction port.
