Abstract:
1. A developing solution supply nozzle supplying a developing solution to a substrate, the nozzle comprising: a main body in a slender shape having a length substantially equal to or larger than a specific direction dimension of the substrate; a developing solution storage chamber extending in said main body in a longitudinal direction of said main body to store the developing solution; a liquid storage chamber extending in said main body in the longitudinal direction of said main body to store a predetermined liquid that is to be mixed in the developing solution; a mixing chamber which extends in said main body in the longitudinal direction of said main body to communicate with said developing solution storage chamber and said liquid storage chamber and in which the developing solution flowing from said developing solution storage chamber and the liquid flowing from said liquid storage chamber are mixed; discharge ports provided in a lower surface of said main body to communicate with said mixing chamber, and having openings arranged along the longitudinal direction to discharge the developing solution mixed in said mixing chamber; a stirring stick extending along the longitudinal direction in said mixing chamber to stir the developing solution and the liquid which flow into said mixing chamber; and a rotation driving section driving said stirring stick to rotate around an axis of said stirring stick.
