Abstract:
1. A substrate treatment apparatus comprising: a substrate holding mechanism which holds a substrate; a nozzle body having a spout which spouts an etching liquid toward a major surface of the substrate held by the substrate holding mechanism; a nozzle body movement mechanism which moves the nozzle body in a predetermined movement direction so as to move an etching liquid application position at which the etching liquid spouted by the nozzle body reaches the major surface; a first single unitary flexible sheet made of a flexible material and attached to the nozzle body, said first flexible sheet being disposed to be brought into contact with a portion of the major surface of the substrate located on one of opposite sides of said nozzle body with respect to the movement direction, the first flexible sheet being extended from the nozzle body so as to be bowed convexly forward with respect to the movement direction with a distal edge thereof being in contact with the major surface; and a second single unitary flexible sheet made of said flexible material and attached to the nozzle body, said second flexible sheet being disposed to be brought into contact with a portion of the major surface of the substrate located on the other of said opposite sides of said nozzle body with respect to the movement direction, the second flexible sheet being extended from the nozzle body so as to be bowed convexly forward with respect to the movement direction with a distal edge thereof being in contact with the major surface.
