  • Publication number: 20040163683
    Abstract: A substrate processing apparatus includes a container in which a heating plate, a discharge nozzle for discharging a vapor of organic solvent, and a discharge nozzle for supplying a process gas and a cooling gas are provided. A pump in communication with an exhaust outlet of the container exhausts an atmosphere from the container to reduce pressure in the container. Therefore, the substrate processing apparatus is capable of performing (1) the process of drying a substrate in a reduced-pressure atmosphere by the use of the vapor of organic solvent, and (2) the process of drying the substrate in the reduced-pressure atmosphere by heating, to thereby efficiently dry the substrate.

In accordance with the process, a processing fluid is selectively applied or excluded from an outer peripheral margin of at least one of the front or back sides or the workpiece. Exclusion and/or application of the processing fluid occurs by applying one or more processing fluids to the workpiece as the workpiece and corresponding reactor are spinning about an axis of rotation that is generally orthogonal to the center of the face of the workpiece being processed. The flow rate of the one or more processing fluids, fluid pressure, and/or spin rate are used to control the extent to which the processing fluid is selectively applied or excluded from the outer peripheral margin.

    Abstract: The invention relates to a device (1) for discharging two or more media with media nozzles (15, 25, 35) in which each media nozzle is located on a media arm (10, 20, 30), with a suspension device for each media arm, so that the media arms can perform pivoting movements separately from one another around same axis (Z). Further, the invention relates to a unit for treating in each case a disk-shaped object (2) with at least two media, with a carrier for holding the disk-shaped object.

  • Patent number: 6352083
    Abstract: A control unit controls a lifter to raise at least part of each of a group of substrates above the liquid level of a treating liquid in a treating bath. Thereafter, a valve is opened to drain the treating liquid from the treating bath at a high speed. As a result, a physical force to tilt and adhere an upper portion of the adjacent substrates accompanied by lowering of the liquid level of the treating liquid due to the high speed drainage acts upon a lower portion of the substrates near the lowered liquid level of the treating liquid, thereby reducing the physical force exerted on the substrates. This arrangement, even if a holding interval between the substrates is narrowed at a half of a normal pitch, eliminates a contact of the adjacent substrates and prevents damage of the substrates due to the contact without providing an additional member such as a substrate support guide in the treating bath.

  • Publication number: 20020020430
    Abstract: A system for processing a workpiece includes a base having a bowl or recess for holding a liquid. A sonic energy source, such as a megasonic transducer, provides sonic energy into a liquid in the bowl. A process reactor or head holds a workpiece between an upper rotor and a lower rotor. A head lifter lowers the head holding the workpiece into the liquid. Sonic energy is provided to the workpiece through the liquid, optionally while the head spins the workpiece. The liquid may include de-ionized water and an etchant.

  • Patent number: 6341612
    Abstract: A cleaning unit (A) includes a movable cart (20) which carries a cleaning system for cleaning baked-on residues from walls (10) of a sterilizer chamber (12). Alkaline and acid cleaning solutions (180, 182), for removing organic and inorganic residues, respectively, from the chamber, are stored in a multi-compartment container carried by the cart and having two storage compartments (52, 54). The alkaline and acid solutions are sequentially sprayed over the chamber walls and returned to their respective compartments. After cleaning is complete, a wall (200) which separates the two compartments is punctured. The two cleaning fluids are thereby mixed together to form a neutral or near neutral solution which is disposable in a sanitary sewer system without further treatment.

  • Patent number: 6267142
    Abstract: A solution delivery system for use with a wafer preparation system is provided. The solution deliver system includes a de-ionized water (DIW) dispense drawer having an input for receiving an initial flow of DIW from a facility water supply. The DIW dispense drawer further includes a first pressure regulator for stabilizing the initial flow of DIW and producing a substantially steady flow of DIW as a DIW output of the DIW dispense drawer. A chemical drawer is also provided as part of the solution delivery system. The chemical drawer is configured to receive the substantially steady flow of DIW from the DIW dispense drawer. The chemical drawer is further configured to receive an initial flow of chemicals from a chemical source. The chemical drawer also includes a second pressure regulator for stabilizing the initial flow of chemicals from the chemical source and thus producing a substantially steady flow of chemicals.

  • Patent number: 6261427
    Abstract: A method, apparatus and system for fabricating a stencil mask for ion beam and electron beam lithography are provided. The stencil mask includes a silicon substrate, a membrane formed from the substrate, and a mask pattern formed by through openings in the membrane. The method includes defining the mask pattern and membrane area using semiconductor fabrication processes, and then forming the membrane by back side etching the substrate. The apparatus is configured to electrochemically wet etch the substrate, and to equalize pressure on either side of the substrate during the etch process. The system includes an ion implanter for defining a membrane area on the substrate, optical or e-beam pattern generators for patterning various masks on the substrate, a reactive ion etcher for etching the mask pattern in the substrate, and the apparatus for etching the back side of the substrate.

  • Patent number: 6235125
    Abstract: An industrial sponge device and a method of manufacturing the same. The sponge is made from a polyvinyl acetal material with a process in which the pores are formed by gas to provide an open pore structure having no fibrils. Additionally, the sponge is purified by an extracting process which includes alternating exposure of the partially cross-linked sponge to solutions of high pH and low pH. The sponge is sterilized by electron beam radiation to destroy micro organisms that can cause contamination of the final product. The resulting sponge material is formed into an industrial sponge having a cylindrical body and a plurality of projections extending from the body. The projections are tapered truncated cones having a cross-sectional radius that decreases with distance from the body. The extracting process permits residual amounts of calcium, zinc, and other elements to be 2 ppm or less preferably 1 ppm or less.

  • Patent number: 6170496
    Abstract: An apparatus for servicing a wafer chuck such as an electrostatic chuck that is equipped with vent holes for cooling the backside of a wafer positioned on the chuck and for clearing the vent holes is provided. The novel apparatus can be used either in replacing a gas supply conduit to the electrostatic chuck without having to break vacuum in the process chamber, or can be used in clearing the vent holes when servicing an electrostatic chuck. The apparatus consists of a three-way control valve and a high pressure gas supply line of a suitable inert gas.
