  • Publication number: 20070068451
    Abstract: Pattern deduction processes of prior art include, after applying a solution reacting with a resist pattern on a surface of the resist pattern, a step of heating a substrate to accelerate the reaction between the resist pattern and the applied film. However, heating for the acceleration of reaction necessarily accompanies conveyance of substrates onto a hot plate. The present invention provides an application apparatus which is provided with a temperature raising means for raising a temperature of the resist pattern reduction material in the vicinity of a nozzle for dropping the resist pattern reduction material.
