    Abstract: An apparatus and a method for reducing solvent residue in a solvent-type dryer for drying semiconductor wafers have been disclosed. The apparatus is constructed by a tank body, a wafer carrier, an elevator means, a tank cover, a solvent vapor conduit and an exhaust means. The exhaust means is provided for fluid communication with a compartment in the tank cover such that any residual solvent vapor or any organic residue in the compartment left from the wafer drying cycle can be evacuated to a factory exhaust system. The present invention novel method for reducing solvent or organic residue in the dryer can be carried out, after the removal of the dried wafers from the dryer, by evacuating the compartment in the tank cover for a time period of between about 30 sec. and about 300 sec. until all residual solvent vapor or organic residue is evacuated.

  • Publication number: 20020038520
    Abstract: A method for drying a polyacrylamide gel, the method comprising contacting the gel with an aqueous solution of a polyhydoxy alcohol other than a polyhydroxy alcohol having at least 3 vicinal hydroxy groups and drying the gel. Examples of suitable polyhydroxy alcohols include 1,2-ethane diol, 1,2-propane diol, 1,3-propane diol, 1,4-butane diol, 1,6 hexane diol, alkyl triol, 1,2,6-trihydroxy hexane, trimethylol propane and pentaerythritol. The gel may be dried between two cellophane sheets positioned in a drying frame arrangement.

  • Patent number: 6249989
    Abstract: A method and apparatus of heating or cooling a charge of a solid material are disclosed. The method includes the steps of supplying a charge of the material to form a packed bed of solids in a process vessel having one or more passageways through which a heat transfer fluid can flow, passing a heat transfer fluid through the one or more passageways and supplying a working fluid to said vessel. The method is characterized by circulating the working fluid through the bed, the circulation step including removing at least part of the working fluid from one or more sections of the vessel and then returning the working fluid to other sections of the vessel.

  • Patent number: 6240655
    Abstract: A method for treating a descending process flow and a spherical-shaped semiconductor integrated circuit manufacturing system incorporating the same. The manufacturing system includes a first processing station, a second processing station and first and second intermediate stations positioned between the first and second processing stations. The first processing station produces, at an output thereof, a first process flow comprised of a first process fluid and spherical-shaped semiconductors. The output of the first processing station is coupled to a first downwardly descending tube which forms an input tube of the first intermediate station. The first process flow enters a porous tube positioned inside an evacuation chamber.

  • Patent number: 6185841
    Abstract: A method and apparatus for heating or cooling a solid material (93) in a process vessel (80) is disclosed. The Method includes supplying a working fluid to a vessel which holds a packed bed (93) of the solid material. The method is characterised by reversing the flow of the working fluid to enhance heat transfer between a heat exchange fluid and the solid material.

  • Patent number: 6132811
    Abstract: The invention relates to a procedure applicable for drying substrate surfaces of a large number of materials, such as semiconductors, metals, plastics and, in particular, silicon. The silicon (1) is dipped into a liquid bath (2) and the silicon (1) is separated from the liquid (3), the liquid of the bath (2) consisting of an aqueous HF solution (3) with a concentration between 0.001 and 50%. By removing the silicon from the bath at a speed of between 0.1 cm/sec and 20 cm/sec, the bath liquid drains from the hydrophobic surface to provide a clean, dry substrate.

  • Patent number: 6105274
    Abstract: A process for treating a workpiece. The workpiece is cooled by directing toward the workpiece a material that includes a gas and particles of a material that undergoes a phase change when applied to the workpiece. The gas and the particle material are non-reactive with the workpiece during the cooling.

    Abstract: The invention relates to a procedure applicable for drying substrate surfaces of a large number of materials, such as semiconductors, metals, plastics and, in particular, silicon. The silicon (1) is dipped into a liquid bath (2) and the silicon (1) is separated from the liquid (3), the liquid of the bath (2) consisting of an aqueous HF solution (3) with a concentration between 0.001 and 50%. By adding a gas mixture containing O.sub.2 /O.sub.3 immediately after the drying process is finished, the silicon surface is hydrophilized. By adding a gas mixture containing O.sub.2 /O.sub.3 during the drying process, cleaning takes place as the ozone enters the solution on the liquid surface.
