Patent ID: 6884298

Claim:
A coating and developing treatment system for performing coating and developing treatment comprising: a coating treatment unit is configured to form a resist film on a substrate; a developing treatment unit configured to develop the substrate; a heating/cooling unit comprising a heat plate configured to continuously heat and a cooling plate configured to continuously cool in one casing the substrate on which the resist film has been formed by the coating treatment unit; and a gas nozzle configured to supply a treatment gas to the resist film formed on the substrate to form a protective film on a surface of the resist film, wherein the gas nozzle is disposed on a cooling plate side in the heating/cooling unit, wherein the gas nozzle is configured to supply the treatment gas after cooling at the cooling plate before an exposure of the substrate, and wherein the gas nozzle is configured to move to a position above the substrate on the cooling plate after cooling at the cooling plate, to supply the treatment gas.
