  • Patent number: 8020599
    Abstract: A method for mounting a film, used to fabricate a mask for use in screening an electronic device, to a common carrier frame. The common carrier frame has an outer edge along an outer periphery and an opening in a central portion of the frame. The method includes applying external pressure to the frame outer edge to compress the frame inward and reduce the opening, securing a film to the frame, the film covering the frame opening, and releasing the pressure on the frame to expand the opening and place the film in tension.

  • Patent number: 8007626
    Abstract: A method of bonding a capillary tube made of a thermally deformable material to a passage in a glass wafer comprising the steps of treating the surface of the capillary tube to render the surface bondable and wettable by a conventional epoxy resin; inserting a support inside the capillary to prevent inward deformation of the capillary during subsequent fabricating steps; inserting the supported capillary inside the port on the wafer; heating an end of the capillary proximate a bottom portion of the port to effect melting of a portion of the heated end of the capillaries; moving the melted end of the capillary into contact with a wall of the port at a desired location for the capillary in the port, thus forming a temporary seal between the capillary and the wall of the port; and introducing an epoxy around the capillary to bind the capillary to the wafer.

  • Patent number: 7998296
    Abstract: A method of protecting a bond layer in a substrate support adapted for use in a plasma processing system. The method includes the steps of attaching an upper member of a substrate support to a lower member of a substrate support with a bonding material. An adhesive is applied to an outer periphery of the upper member and to an upper periphery of the lower member, and a protective ring is positioned around the outer periphery of the upper member and the upper periphery of the lower member. The protective ring is originally fabricated with dimensions the provide mechanical stability and workability. The protective ring is then machined to an exact set of final dimensions consistent with the design of the substrate support application.

  • Patent number: 7998304
    Abstract: Methods configure a proximity head for conditioning fluid flow relative to a proximity head in processing of a surface of a wafer by a meniscus. The methods configure the head in one piece while maintaining head rigidity even as the head is lengthened for cleaning of large diameter wafers. The one-piece head configuring separates main fluid flows from separate flows of fluid relative to the wafer surface, with the separation being by a high resistance fluid flow configuration, resulting in substantially uniform fluid flows across increased lengths of the head in a unit for either fluid supply or return.

  • Patent number: 7981235
    Abstract: A cellular structure is formed on a wheel from an elongated tubular structure. At least one longitudinal line of a slow cure adhesive is applied to the exterior surface of the elongated tubular material. Then the material is wrapped around a collector in a manner to cause the adhesive to be positioned between overlying surfaces of the elongated tubular material and to form a cellular structure on the collector. The cellular structure is cut from the collector before the adhesive has fully cured and is placed on a flat surface where the adhesive has fully cured.

  • Patent number: 7967932
    Abstract: The invention provides an improved method for forming a composite material mainly composed of carbon fiber. It is difficult to form an H-shaped structural member formed of a prepreg material having carbon fiber fabric impregnated with epoxy resin into a member having curvature. Thus, the structural member is divided into two bendable constructional elements 110 and 120, which are bent to given curvature then adhesively-bonded to form a structural member having curvature.

  • Patent number: 7951318
    Abstract: Tooling aids for applying pressure in laminating, and methods for their use, are described herein. In one embodiment, a caul for applying pressure in laminating includes a base portion positioned between first and second corner portions. The base portion can have a curved shape when it is in a relaxed state, but it moves to a flatter shape when subjected to pressure during lamination. Movement of the base portion to the flatter shape causes the first and second corner portions to move outwardly and away from the base portion. In this manner, the caul can be used to compact laminating materials into corner regions of a corresponding female mold surface.

  • Patent number: 7947149
    Abstract: A web of a first sheet material and a web of a second sheet material are laminated together by a process wherein the sheet materials are wound, in an interleaved relationship, upon a roller having a radially displaceable outer surface. The roller and webs and then subjected to heating and/or a low-pressure environment so as to complete the lamination. A body of adhesive material, such as a hot melt adhesive, may be interposed between the webs and the heating or low pressure environment can activate this adhesive. Further disposed are particular configurations of rollers with radially displaceable surfaces.

  • Patent number: 7942993
    Abstract: In a method, multilayer tailored fiber placement (TFP) preforms of any desired thickness may be easily produced without fixing threads or intermediate layers interfering. Reinforcing fibers are sewn onto a substrate using a chemically or thermally meltable fixing thread thus resulting in the formation of a reinforcing fiber structure. The fixing thread firstly serves to fix the reinforcing fibers on the substrate and is subsequently melted so that the fixing thread disintegrates while pre-fixing the reinforcing fibers and may not influence the mechanical properties of the reinforcing fiber structure.
