发明名称 COATING METHOD AND COATING APPARATUS
摘要 <p>The present invention provides a coating method and apparatus capable of stably performing the thickness control of a coating film in a spinless fashion particularly the uniformalization of film thickness at the coating scanning terminal part with an excellent reproducibility. The discharge pressure of the resist nozzle(78)starts to be attenuated at the point of time ta when a fixed delayed time is elapsed after a resist pump is stopped at the point of time t1 when a resist nozzle 78 is passed through a passing point X1. The upward movement of the resist nozzle 78 with respect to a substrate Gand the attenuation of the scanning speed start respectively at each of a prescribed time point t2, t3 near to the attenuation of the discharge pressure of the resist nozzle 78. In the mid time whenthe discharge pressure of the resist nozzle 78 is attenuated, the resist nozzle 78 is moved upward and the scanning speed is decreased.</p>
