  • Publication number: 20080224314
    Abstract: A cap layer for a metal feature such as a copper interconnect on a semiconductor wafer is formed by immersion plating a more noble metal (e.g. Pd) onto the copper interconnect and breaking up, preferably by mechanical abrasion, loose nodules of the noble metal that form on the copper interconnect surface. The mechanical abrasion removes plated noble metal which is only loosely attached to the copper surface, and then continued exposure of the copper surface to immersion plating chemicals leads to plating at new sites on the surface until a continuous, well-bonded noble metal layer has formed. The method can be implemented conveniently by supplying immersion plating chemicals to the surface of a wafer undergoing CMP or undergoing scrubbing in a wafer-scrubber apparatus.

    Abstract: A method is disclosed to measure the permeability of films or coatings towards solvents (e.g. water). First a substrate comprising an absorption or container layer is provided, preferably the material is a porous material. To study water permeability, the porous material is hydrophilic or is made hydrophilic by means of e.g. an anneal process. To study the permeability of the film or coating, the coating is deposited on top of the porous material. The substrate comprising the film or coating on top of the absorption or container layer is then brought into a pressurizable chamber subsequently filled with the gaseous substance of the solvent (e.g. water vapor). By increasing/decreasing the vapor pressure in the chamber between zero and the equilibrium vapor pressure of the solvent used, the permeability (penetration) of solvent through the film or coating can be determined. The amount of solvent that can penetrate through the film or coating can be measured by means of ellipsometry, mass spectrometry, etc.

The work tank is equipped with a heater to keep the temperature of the fluid and the preservative in the work tank at a predetermined level. Hot fluid and preservative is drawn under a vacuum, initially from the work tank. On filling a pressure vessel, a pressure pump then supplies the preservative and fluid mixture under pressure to the pressure vessel in which the wood or wood product is being treated. As the treatment process depletes the preservative in the fluid, through absorption in the wood, the depleted fluid is circulated back to the work tank where it is heated and more preservative is added to restore the concentration of preservative in the fluid to a desired level. The fluid, replenished with preservative, is then pumped into the pressure vessel.

  • Publication number: 20040055535
    Abstract: A diptank applies coating solution to devices that are dipped therein. A reservoir tank contains a reservoir of coating solution. The diptank forms a coating solution overflow return that flows to the reservoir by means of a conduit and a self-adjusting return line. The self-adjusting return line comprises a plastic tubing with an upper portion, a central portion and a lower portion. The upper portion is coupled to the conduit. The tubing central portion is flexible and corrugated and arranged to extend and compress in its length. The lower portion is supported by an attached buoy that floats on the surface of the reservoir. The lower portion defines an outlet that discharges the coating solution overflow return to the reservoir. As a result, the coating solution overflow return is discharged to the reservoir at a fixed vertical distance or level with respect to the surface of the reservoir.

  • Publication number: 20040055534
    Abstract: An applicator apparatus for applying a preferably foamed treating fluid to a traveling permeable fabric, web or other substrate can include either or both of a low-pressure exhaust chamber on the opposite side of the substrate from the applicator nozzle and a flexible lip extending from either or both sides of the nozzle opening, between the nozzle and the substrate. The applicator apparatus is particularly adapted and well-suited for lightly coating or treating the surface of a fragile and fast moving substrate, without deformation or breakage of the substrate and without undesirable substrate penetration.

  • Publication number: 20040050323
    Abstract: An apparatus for controlling coating weight on a steel strip in a continuous hot dip galvanizing process, in which the coating weight is controlled through air wiping after the steel strip passes through a molten zinc coating bath. More particularly, the apparatus keeps the steel strip equidistant from each air knife, uniformly distributes a spray pressure of the air knives in a widthwise direction of the steel strip, and minimizes variation in coating weights on both surfaces of the steel strip. Furthermore, when two steel strips that are different in thickness are continuously hot dip galvanized, the apparatus predicts the movement of the passing line of the steel strips and accurately controls the positions of the air knives. As a result, product deficiencies such as insufficient coating can be reduced and zinc loss due to excess coating can be minimized.

  • Publication number: 20040052960
    Abstract: The subject of the invention is a process for the continuous dip-coating of a metal strip (1) in a tank (11) containing a liquid metal bath (12), in which process the metal strip (1) is made to run continuously through a duct (13), the lower part of which is immersed in the liquid metal bath (12), in order to define with the surface of the said bath a liquid seal (14). In the region where the strip (1) leaves the liquid metal bath (12), the liquid metal is isolated from the surface of the said bath in an isolating enclosure (20) and the metal oxide particles and intermetallic compound particles are recovered by the liquid metal flowing from this region into the said enclosure (20) and the said particles are extracted from this enclosure (20).
