Abstract
A method of supplying a developing solution is provided. The method includes supplying a developing solution onto a substrate from a first developing solution nozzle, so as to form a ribbon-like region on the surface of the substrate, while rotating the substrate about a vertical axis via a substrate holding part. The method further includes shifting a position of the ribbon-like region in which the developing solution is supplied. Developing solution is supplied from a second developing solution nozzle, so as to form a circular region on the central portion of the substrate or form a ribbon-like region shorter in length than the ribbon-like region of the developing solution supplied from the first developing nozzle. Simultaneously, the substrate is rotated about the vertical axis via the substrate holding part, thereby spreading the developing solution toward a peripheral portion of the substrate by centrifugal force.
