  • Fluid treatment apparatus and method
    Patent number: 5444925
    Abstract: A new apparatus for treating substrates with fluids, as well as a corresponding fluid treatment method, is disclosed. The new apparatus includes a new configuration of fluid jet injectors which substantially overcomes the problem of dragout, in which fluid impinged upon an area of a substrate is retained on that area, preventing fresh fluid from reaching the impinged area. This new configuration also avoids imposing torques on substrates, and substantially reduces the need for rollers and guides for transporting substrates.
