Abstract

In a developing processing to apply the developing solution onto the substrate after the light exposure, a developing solution supply nozzle scans a substrate more than once while discharging the developing solution on the substrate in a band shape to coat the substrate with the developing solution. Thus, it is possible to perform a developing processing with a small variation and high uniformity of the line width.
