ABSTRACT:
A system, method, and apparatus for supplying a gas-liquid vapor to a process tank for performing semiconductor manufacturing. In one aspect, the invention is a method of supplying a gas-liquid vapor to a process tank comprising: supplying a gas stream through at least one hydrophobic tube; exposing the outside surface of the hydrophobic tube to a liquid so that a vapor of the liquid permeates the hydrophobic tube and enters the gas stream, forming a gas-liquid vapor inside the tube; and transporting the gas-liquid vapor to the process tank. In another aspect, the invention is an apparatus for supplying a gas-liquid vapor to a process tank comprising: at least one hydrophobic tube adapted to carry a gas; and a housing forming a chamber that surrounds the tube, the chamber adapted to receive a liquid that can permeate the tube, forming a gas-liquid vapor. In yet another aspect, the invention is a system for supplying a gas-liquid vapor to a process tank comprising: the apparatus of the present invention; gas supply means adapted to supply the gas to the tube; liquid supply means adapted to supply the liquid to the chamber; and gas-liquid transport means adapted to carry the gas-fluid vapor from the apparatus to the process tank.
