Abstract:
An apparatus for providing a photoresist material onto a substrate includes a lid housing at least one nozzle. A solvent supplying port inputs the solvent into the apparatus. A first solvent trap is provided below the nozzle and coupled to the solvent supplying port to hold a given amount of the solvent being input from the solvent supplying port. The first solvent trap is configured to prevent photoresist residues on the nozzle from being converted to powders. A second solvent trap is provided below the first solvent trap to receive the solvent from the first solvent trap. A solvent path is provided between the solvent trap and the solvent container to guide the solvent from the first solvent trap to the second solvent trap.
