Claim 8:
9. A method for developing a resist film on a substrate using a development processing apparatus including:
a substrate holder configured to horizontally hold the substrate;
a rotator configured to rotate the substrate holder around a vertical axis;
first and second developer supplies each configured to supply a developer to the substrate held by the substrate holder; and
a liquid receiver configured to receive the developer from the substrate held by the substrate holder,
wherein the first developer supply has a length smaller than a diameter of the substrate in a plan view,
the second developer supply has a length equal to or larger than the diameter of the substrate in a plan view,
the liquid receiver includes first and second annular walls that are formed in an annular shape having a circular opening having a diameter larger than the diameter of the substrate in a plan view and are configured to be movable up and down, and
the second annular wall is provided above the first annular wall,
the method comprising:
supplying the developer from the second developer supply in a state where the first annular wall and the second annular wall are arranged below the substrate held by the substrate holder, and
supplying the developer from the first developer supply in a state where the first annular wall is arranged above the substrate held by the substrate holder and the second annular wall is arranged at a position farther from the first annular wall than when the developer is supplied from the first developer supply.
