摘要： Disclosed is a bubble removing method in which fine bubbles are removed from a filter to improve the performance of the filter. The bubble removing method includes a step of degassing a processing liquid supplied from a supply source to prepare a highly degassed liquid (highly degassed liquid preparation), a step of supplying the prepared highly degassed liquid at a first processing liquid from a pump device to a filter device (temporary liquid permeation), a step of supplying the highly degassed liquid at a second processing liquid flow rate higher than the first processing liquid flow rate from the pump device to the filter device (initial liquid permeation), and a step of causing the highly degassed liquid to flow from the pump device to the filter device for a predetermined length of time (liquid permeation).

摘要： A substrate processing apparatus according to the present disclosure includes: a nozzle that ejects a processing liquid to a wafer; a force-feeding unit that force-feeds the processing liquid to the nozzle side; a liquid feeding pipeline that includes first and second valves and guides the processing liquid from the force-feeding unit to the nozzle; and a controller. The controller is configured to perform opening the first valve in a state where the second valve is closed and a pressure between the first and second valves is higher than a pressure between the force-feeding unit and the first valve, controlling the force-feeding unit to increase the pressure between the first and second valves that has been decreased by the opening of the first valve, and opening the second valve after the pressure between the first and second valves is decreased by the opening of the first valve.

摘要： A solution supply apparatus is for supplying a treatment solution to a treatment solution discharger which discharges the treatment solution to a treatment object. The solution supply apparatus includes: a supply pipe line connected to the treatment solution discharger; a filter provided on the supply pipe line which filters the treatment solution to remove foreign substances; and a controller. The controller performs a determination of a state of the treatment solution to be supplied to a primary side of the filter and, when the state of the treatment solution is determined to be bad, outputs a control signal for restricting supply of the treatment solution to the primary side of the filter.
