Patent ID: 6918192

Claim:
A system for drying a substrate, comprising: a substrate cleaning tank for containing the substrate; a mixed fluid conduit provided in fluid communication with said substrate cleaning tank for mixing a vaporized drying fluid with nitrogen gas and introducing the vaporized drying fluid mixed with the nitrogen gas into said substrate cleaning tank; a pump provided in fluid communication with said substrate cleaning tank for reducing a gas pressure in said substrate cleaning tank and lowering a boiling point of said drying fluid; a container provided in fluid communication with said mixed fluid conduit for initially containing the drying fluid; a gas mass flow controller interposed between said container and said mixed fluid conduit for controlling flow of the drying fluid in vaporized form from said container to said mixed fluid conduit; and a heat-inducible fluid outlet conduit provided between said container and said gas mass flow controller for maintaining the drying fluid in a vaporized state between said container and said gas mass flow controller.
