    摘要: A resist material dispensing system includes a resist supply and a resist filter connected to the resist supply downstream from the resist supply. The resist material dispensing system includes a resist tank structure connected to the resist filter downstream from the resist filter and a resist pump device connected to the resist tank structure downstream from the resist tank structure. The resist tank structure is vertically arranged so that a resist material flows in a continuous downward flow from where the resist material enters the resist tank structure until the resist material exits the resist tank structure.
