Abstract:
A solution processing apparatus, comprising:a substrate holding portion configured to horizontally hold a substrate having a front surface and a periphery; a supply nozzle configured to move across the substrate held by the substrate holding portion and supply a processing solution to the front face of the substrate; and a solution separation member having a summit portion and surrounding the periphery of the substrate with a clearance between the summit portion of the solution separation member and the periphery of the substrate, and configured to separate the processing solution existing between the periphery of the substrate and the supply nozzle by surface tension from the substrate and allow the processing solution to adhere to the solution separation member while the summit portion of the solution separation member is at a position lower than the front face of the substrate and the supply nozzle leaves the periphery of the substrate outwardly, the solution separation member being made of a material with adhesion to the processing solution stronger than that of the substrate.
