A substrate drying system for drying substrates after the substrates are washed typically using deionized water. The substrate drying system comprises a substrate cleaning tank in which the substrates are washed. A dry pump is provided in fluid communication with the substrate cleaning tank. A container which contains a supply of a liquid drying fluid, typically isopropyl alcohol (IPA), is further provided in fluid communication with the substrate cleaning tank. In application, the dry pump induces a reduced pressure inside the substrate cleaning tank and the drying fluid container. This reduces the vapor pressure, and thus, the boiling point of the drying fluid, such that the drying fluid is vaporized and remains in a vaporized state throughout transit to the substrate cleaning tank and during drying of the substrate.
