Abstract: A fluid-flowing apparatus and a fluid-flowing method using the same are provided to maximize production yield by removing bubbles from fluid inside a nozzle. A semiconductor substrate(120) is supported on a stage(110). An external nozzle(130) is contacted in a surface of the semiconductor substrate, and charges fluid(160). An internal nozzle(140) absorbs and collects the fluid inside the external nozzle. A vibration unit(150) vibrates the internal nozzle. Bubbles(162) are removed from the fluid.
