Patent ID: 7977039

Claim:
A developing treatment method of developing an exposed pattern, said pattern obtained after a resist film formed on a substrate is exposed in a predetermined pattern, said method comprising the steps of: applying a developing solution to the resist film after the exposure to cause development to proceed; rotating the substrate after the development to shake off the developing solution; supplying pure water onto the substrate to clean the substrate with the pure water; supplying a first rinse solution composed of a surfactant with a concentration of 500 ppm to 1500 ppm onto the substrate to clean the substrate with the first rinse solution; supplying a second rinse solution composed of a surfactant with a concentration of 100 ppm to 400 ppm onto the substrate to clean the substrate with the second rinse solution; after said step of cleaning the substrate with the second rinse solution, rotating the substrate for a predetermined time at a first rotation speed to move the rinse solution on the substrate to a periphery of the substrate; and rotating the substrate for a predetermined time at a second rotation speed higher than the first rotation speed to shake off the rinse solution moved to the periphery of the substrate to thereby dry the substrate, thereby restrain variation in pattern line width attributed to pattern collapse, and, at the same time, thereby reduce precipitation-based defects wherein the substrate is rotated at a same predetermined rotation speed while cleaning the substrate with the pure water, cleaning the substrate with the first rinse solution and cleaning the substrate with the second rinse solution are performed, and said same predetermined rotation speed is higher than the first rotation speed.
