  • Method and apparatus for increased recirculation and filtration in a photoresist dispense system using a liquid empty reservoir
    Patent number: 10048587
    Abstract: An apparatus for dispensing a liquid onto a substrate may comprise a reservoir for storing the liquid to be dispensed; a filter comprising an inlet and an outlet, the filter inlet in fluidic communication with the reservoir via a first valve; a dosing pump comprising an inlet, a first outlet, and a second outlet, the dosing pump inlet in fluidic communication with the reservoir and the dosing pump second outlet in fluidic communication with the filter inlet via a second valve, the dosing pump configured to dose an amount of the liquid and pump the liquid; and a dispense nozzle in fluidic communication with the dosing pump first outlet, the dispense nozzle configured to dispense the liquid onto the substrate.
