Abstract:
A liquid treatment apparatus includes: a substrate holder for holding a substrate; a discharge nozzle for discharging a treatment liquid onto the substrate; a liquid supply pipe for supplying the treatment liquid from a treatment liquid storage source to the discharge nozzle; a gas pipe that encompasses the liquid supply pipe and through which an inert gas for adjusting the temperature of the treatment liquid flows in a space between the gas pipe and the liquid supply pipe; a processing container in which the substrate holder, the discharge nozzle, the liquid supply pipe, and the gas pipe are provided; and an atmosphere gas supply part for supplying an atmosphere gas into the processing container. The gas pipe is provided so that an extension portion between an upstream end inside the processing container and an encompassing portion is folded back inside the processing container in a plan view.
Abstract:
A tank includes a container part having an upper wall, a sidewall and a bottom wall to store a processing liquid therein, a liquid discharge passage installed at a position higher than a liquid surface of the processing liquid stored in the container part to discharge the processing liquid into the container part, and a gas discharge passage installed at a position higher than the liquid surface to discharge a gas into the container part. The liquid discharge passage discharges the processing liquid from the liquid discharge port so that the processing liquid is brought into contact with a portion above the liquid surface of an inner surface of the sidewall. The gas discharge passage discharges the gas from the gas discharge port so that the gas is brought into contact with a portion above the liquid surface of an inner surface of the container part.

Abstract:
A liquid can be delivered with a simple configuration. A liquid delivery method includes allowing a liquid to flow in a tube having elasticity depending on a pressure of a gas filled in an inner space between a tube housing covering an outside of the tube and an outer surface of the tube; obtaining a magnitude of a pressure of the liquid flowing in the tube as a first value; obtaining a magnitude of the pressure of the gas filled in the inner space as a second value; calculating a difference between the first value and the second value as a third value; and detecting a status of the tube on the basis of the third value.

Abstract:
In one embodiment, a feed pump of a tube pump type is used for supplying a processing liquid. The tube pump has a squeezing member that moves from a first axial position of a tube at which the squeezing member starts pinching of the tube, to a second axial position at which the squeezing member leaves the tube after feeding the processing liquid toward an ejecting part such as a nozzle. Only one pinched part pinched between the squeezing member and a guide member is formed between the first axial position and the second axial position of the tube, and the only one pinched part moves along the axial direction of the tube, during feeding of a dose of the processing liquid toward the ejecting part.
