Abstract:
PURPOSE: A substrate processing method, a storage medium storing a computer program for implementing the substrate processing method and a substrate processing apparatus are provided to improve a processing speed by supplying a chemical solution to a wafer. CONSTITUTION: A chemical solution is supplied to a substrate. A rinsing solution is supplied to the substrate. The substrate is dried. The substrate is rotated with a first rotation number in a first drying process. The substrate is rotated with a second rotation number in a second drying process. The first rotation number is larger than the second rotation number. [Reference numerals] (AA) Revolution number(rpm); (BB) Rinse process; (CC) First drying process(surface substitution); (DD) Third drying process(overall substitution); (EE) Fourth drying process(IPA scattering); (FF) Second drying process(agitation); (GG) Time(sec)
Abstract:
The present invention provides a liquid processing apparatus and a liquid chemical collecting method for preventing corrosion of a wiring provided on a substrate. The liquid processing apparatus according to an embodiment includes a processing unit, a collecting pipe, a supply pipe, and a gas supply unit. The processing unit performs liquid processing by supplying liquid chemical to the substrate. The collecting pipe collects the liquid chemical supplied to the processing unit. The supply pipe supplies the collected liquid chemical to the processing unit. The gas supply unit supplies inert gas to the inside of the collecting pipe.
