Patent ID: 8376637

Claim:
A photoresist coating and developing apparatus that forms a photoresist film on a substrate and develops the photoresist film, the apparatus comprising: a photoresist film forming unit that forms the photoresist film on the substrate; a first heating unit that heats the substrate on which the photoresist film has been formed by the photoresist film forming unit; a cooling unit that cools the substrate to normal temperature, the photoresist film having been formed on the substrate, the substrate having been heated by the first heating unit; a second heating unit that heats the substrate to a predetermined temperature prior to exposing the photoresist film, the substrate having been cooled to normal temperature by the cooling unit and having been transferred from the cooling unit; a first load-lock chamber that unloads the substrate under depressurized atmosphere to expose the photoresist film; and a first transfer unit that transfers the substrate from the second heating unit to the first load-lock chamber, wherein two pre-baking processes are performed on the substrate by the first heating unit and the second heating unit at different times.
