Abstract
An apparatus is configured to perform a solution process by supplying a processing solution from a processing solution supply source to the substrate held on a substrate holder via a flow path member and a nozzle at a flow rate equal to or less than 1 mL/sec. The apparatus includes a solution transfer unit configured to transfer the processing solution to the nozzle, and connected to the flow path member, and an ultrasonic flowmeter connected to the flow path member at an outlet side from the solution transfer unit. In this embodiment, a lower limit of a flow rate range which is measured by the ultrasonic flowmeter is equal to or less than 1 mL/sec.
