Abstract
When the surface of a substrate is developed, a developing solution in low state of development function is supplied to the surface of the substrate. Thereafter, the development function of the supplied developing solution is improved. Thus, the surface of the substrate is developed. When the developing solution is supplied to the surface of the substrate, the developing solution does not develop the surface of the substrate. Thus, even if there is a time lag of the developing solution supplied on the surface, the surface of the substrate is equally developed.
