Abstract:
An apparatus for forming a photoresist film in a semiconductor device, comprising:a photoresist coating unit for coating a photoresist on a wafer;a first chamber in which a nitrogen gas of high pressure and low temperature is dispersed for planarizing a surface of the photoresist film formed on said wafer, said first chamber connected to said photoresist coating unit; anda second chamber in which a dried nitrogen gas of high temperature is dispersed for removing a solvent contained within the photoresist film and for baking the photoresist film, said second chamber connected to said first chamber, wherein during the baking process in the second chamber, heat is transferred from the photoresist film to the wafer by dispersing the dried nitrogen gas of high temperature from a nozzle at an upper side of the second chamber.
