Abstract:
A semiconductor fabricating device, comprising:an adhesion unit installed on a base body in a production line, the adhesion unit having an adhesion chamber that supplies an adhesion enhancing material that reinforces adhesion between a wafer and a photoresist layer when the photoresist layer is deposited on the wafer and that generates a process deteriorating gas; a cooling unit installed in the production line to cool down the wafer transferred from the adhesion unit; and a bake unit installed in the production line, the bake unit being adapted to bake the wafer having the photoresist layer formed thereon, the baking being susceptible to operational failures if exposed to the process deteriorating gas, wherein the bake unit and the cooling unit are installed at a higher level than the adhesion unit, and wherein clean air flows downward over the adhesion, cooling, and bake units to carry the process deteriorating gas away from the bake unit and cooling unit.
