Patent ID: 6928750

Claim:
A system for drying a wet substrate with a mixture of gas and vaporized liquid comprising: a process tank having a wet substrate to be dried by contact with said mixture supported therein; a gas source; a liquid isopropyl alcohol source; at least one hydrophobic tube fluidly connected to the gas source, the hydrophobic tube being impermeable to said liquid but permeable to the vapor of said liquid; a housing forming a chamber that surrounds the tube, the chamber fluidly connected to the liquid source; means for supplying the gas to the at least one hydrophobic tube from the gas source; means for supplying the liquid to the chamber from the liquid source, a vapor of the liquid permeating the at least one hydrophobic tube and forming a mixture of the gas and vaporized liquid in the at least one hydrophobic tube; and means for transporting said mixture from the inside of the hydrophobic tube to the wet substrate supported in the process chamber.
