  • Patent number: 6108932
    Abstract: A method for thermocapillary drying of substrates includes the step of elevating a submerged substrate away from a rinsing liquid. Such movement of the substrate forms a meniscus on opposite sides of the substrate. The curved raised portion of the meniscus at each side of the substrate is gently heated in such a way as to induce thermocapillary flows, which cause the rinsing fluid to flow away from the substrate so that the withdrawing substrate may be pulled out dry and clean. Heating may be accomplished by directing a warm gas onto the meniscus or by heating the meniscus with rays from a radiation/light source. Apparatus is also provided for performing the various method steps.

  • Patent number: 5954068
    Abstract: A device for treatment of substrates in a fluid container includes a container containing a treatment fluid and a substrate transport device moveable into a position above the container. The substrate transport device has at least one substrate holding device for securing the substrates in a first position and releasing the substrates in a second position. A third position may be provided in which a first set of substrates is secured and a second set of substrates is released. The substrate holding device is preferably at least one rotatable securing rod.

  • Patent number: 5902402
    Abstract: A device for chemical wet treatment of substrates has a tank containing a treatment fluid for treating the substrates. At least one substrate carrier for supporting the substrates within the tank is provided. At least one substrate lifting device for lifting the substrates off the substrate carrier is provided. A lifting apparatus for lifting and lowering the substrate carrier is positioned in the tank. The lifting apparatus has a first transport carriage connected to the substrate lifting device and a second transport carriage connected to a holder of the substrate carrier. The first and second transport carriages are connected to one another by a jointed connection.

  • Patent number: 5879464
    Abstract: A method and device for the wet processing of substrates in a container are provided. At least one liquid is introduced via at least one liquid inlet into the container. A liquid overflow device is adapted to float on the surface of the liquid in the container. The overflow device is provided with openings for withdrawing liquid from the container. Accompanied by release or flooding of the substrates disposed in the container, the overflow device, together with the surface of the liquid, drops to below the substrates or is raised from the substrates.

  • Patent number: 5455062
    Abstract: A device for coating a plate has an open channel being open in an upward direction and a device for supplying a liquid to the open channel. The liquid in the open channel forms an convexly curved portion projecting upwardly from the open channel. A device for transporting a plate at a close distance past the open channel is provided, with which a surface to be coated of the plate facing the convexly curved portion of the liquid is guided such that a thin film of the liquid is deposited on the surface to be coated by adhesion effects. Another device for lacquering or coating plates or disks has a capillary slot that is filled with a liquid coating medium. The plate to be coated is advanced across the capillary slot with the surface to be coated facing downwardly so that due to the capillary effect a thin layer is deposited on the surface of the plate.
