Abstract: A supply device includes a collect tank which collects a process liquid from a substrate processing device and heats the collected liquid, and a supply tank connected to the collect tank and which supplies, to the substrate processing device, the process liquid heated in the collect tank. The collect tank includes a collect container that stores the process liquid, a first dividing plate that divides the collect container into a first region where the process liquid is introduced from the substrate processing device, and a second region that introduces the process liquid to the supply tank, piping that feeds, to the second region, the process liquid introduced in the first region, a first heater provided on a path through the piping and which heats the process liquid, and feed piping that feeds, to the supply tank, the process liquid in the second region and heated by the first heater.

Abstract: According to one embodiment, a processing liquid supply device includes: a tank that stores the processing liquid; a supply path that supplies the processing liquid to the processing device; a heater that heats the processing liquid; a thermometer that measures a temperature of the processing liquid; a densitometer that measures a concentration of the processing liquid; and a controller including an inspecting unit that inspects the densitometer. The inspecting unit includes: a temperature setting device that sets a boiling point temperature at which a predetermined concentration is reached as a predetermined temperature; a heating controller that heats the processing liquid by the heater so as to reach a target temperature within a predetermined range; and a determination device that determines whether or not the concentration of the processing liquid is a target concentration within a predetermined range based on the predetermined concentration.
