Abstract

PURPOSE:To lessen the drip amount and suppress the evaporation of a volatile solvent into the air, by reducing its drip time and then improve the uniformity of a photoresist film thickness, by composing a nozzle so that more than two dropping holes are arranged at least. CONSTITUTION:Photoresist 101 is dropped from the tip 3 of a nozzle to a wafer through a filter 2. In such a case, a plurality of drip holes 102 are arranged at the tip 3 of the nozzle and photoresist 101 is dropped to spread over the whole water through a plurality of the drip holes 102. As a result, the drip amount of photoresist can be curtailed in comparison with that of the conventional nozzles for dropping photoresist and also its drip time is reduced. Then this nozzle may suppress the evaporation of a volatile solvent in photoresist into the air and not only makes photoresist film thicknesses uniform but also forms fine patterns which exhibit an excellent reproducible property.
