Patent ID: 8518480

Claim:
A method of developing a resist film on a substrate using a developing solution at a predetermined temperature lower than room temperature using a developing treatment system, comprising: a cooling apparatus including a cooling plate mounting and cooling the substrate thereon; a developing apparatus including a developing solution nozzle supplying the developing solution onto the substrate, and a rinse solution nozzle supplying a rinse solution at the predetermined temperature or lower onto the substrate; a solution supply apparatus including a temperature regulating pipe for regulating the developing solution to the predetermined temperature, and the temperature regulating pipe having a triple pipe structure including a first pipe, a second pipe surrounding the first pipe, and a third pipe surrounding the second pipe; and a control unit controlling said developing treatment system and performing method steps as follows: a first cooling step of mounting and cooling the substrate on the cooling plate at a temperature lower than room temperature and higher than the predetermined temperature in a cooling apparatus; a second cooling step of supplying a rinse solution at the predetermined temperature or lower onto the substrate to cool the substrate in the developing apparatus; a developing step of then supplying the developing solution from the developing solution nozzle onto the substrate and developing the resist film on the substrate to form a resist pattern in the resist film, the developing step including flowing the developing solution through the first pipe, flowing a temperature regulating water flowing between the first pipe and the second pipe that regulates the developing solution to the predetermined temperature, and forming an air layer between the second pipe and the third pipe; and a cleaning step of then supplying a rinse solution at the predetermined temperature from the rinse nozzle onto the substrate to clean a front surface of the substrate.
