A fastener assembly includes a bolt (1) having first and second ends and comprising a bolt head (2) at the first end and a shank, at least a part of which is screw threaded, a nut (12) for screw threaded engagement with the shank of the bolt (2), and a template alignment pin (30), wherein the bolt head (2) is provided with a coupling formation (27, 28) for detachably coupling to a corresponding formation (31, 32) on the template alignment pin (30).
Abstract:
The invention describes the ability to conduct multiple carrier substrate removal practices simultaneously. The fixture design is slotted in a manner to hold film frame rings and has the bottom region open without interference to the passage of the released carrier substrate. Slots in the fixture are arranged on two sides at top and bottom to support the film frame, however, the distance between the slots and the area of the open region is sufficient to allow the carrier substrate to travel downwards under gravity force, once it has been released from the device wafer. The method describes a batch process whereby a fixture design supports multiple film frames with taped adhered device wafers enable exposure to a chemical medium that either acts upon the interface between the device wafer and carrier substrate or digests the carrier substrate in a manner that results in removal.
Abstract:
Compositions and methods are described for a release layer that is affixed directly onto a carrier or with the use of an interfacial adhesive layer to fabricate a flexible work product, and upon completion, the release layer is removed by an external applied force of a given value that overcomes the adhesive force without harm to the work product. The release layer serves as a permanent support for the manufacture of flexible electronic devices and upon completion offers a simple means to achieve a wide range of thin and ergonomically pleasing options for the consumer. The invention provides benefits of flexibility in choosing a host of materials to meet the needs of a specific manufacturing objective and rapidly moving towards the next step in the manufacture of semiconductors and flat panel displays.
Abstract:
The present invention is a concentrated chemical composition to remove photoresist during microelectronic fabrication that includes one or more active species which exhibit acidic or alkaline chemical properties that affects the photoresist removal performance, one or more inhibitor or protecting agents to an underlying substrate or one or more metal features to protect the substrate and one or more surface active agents providing sufficient wetting of the substrate without producing a foam level which prohibits sufficient tool performance. The concentrated chemical composition also includes one or more solvents and one or more carrier solvents to keep the formed chemical composition in a liquid form.
Abstract:
A dangerous goods repository checking system comprises a user identifier device for identifying a user accessing a repository, arranged to output user data indicative of an identity of said user; a dangerous goods identifier device for identifying dangerous goods checked into or out of the repository, arranged to output goods data indicative of an identity of said dangerous goods; and a data storage configured to receive and record the user data and the goods data when the identified user checks the dangerous goods into or out of the repository.
Abstract:
A rib bay platform (1) for use in an aircraft rib bay, is adjustable in length (for example it comprises two telescopically mounted sections (3, 5). The platform (1) comprises a first end (7) configured for mounting on a stringer of the rib bay (for example by an interference fit), and a second end (9) configured for mounting on another stringer of the rib bay (for example on feet mounted on ball-and-socket joints). A method of operating in an aircraft rib bay comprises the steps of providing a rib bay platform of adjustable length; adjusting the length of the platform; mounting the platform between the two stringers; whereby a person may then operate inside the aircraft rib bay whilst being supported on the platform.
Abstract:
Compositions and methods are described for a temporary adhesive with adjustable adhesion force to affix a thin solid material onto a carrier whereby the force of adhesion is defined by choosing and adjusting the polymeric resin components to provide sufficient adhesion to support a manufacturing process, and upon completion, the thin solid material is removed by an external applied force of a given value that overcomes the adhesive force without harm to the thin solid material. The temporary adhesive provides a tunable adhesion force that is lower than the tensile strength of the thin solid material, preferably less than 50%, more preferably less than 25%, and most preferably less than 10% of the tensile strength of the thin solid material. The temporary adhesive may be applied and cured in a variety of ways that meet the needs of the form of the thin solid material and objectives of the manufacturing process. The invention provides benefits of flexibility and reduced cost when establishing practices to handle difficult thin solid materials in the manufacture of semiconductors and flat panel displays.

An analyte sensor is described. The sensor employs a single sensor element which provides a plurality of phase outputs in response to excitation by a modulated excitation source. The plurality of phase outputs may be analysed to provide information on the presence of one or more analytes.
Abstract:
A fastener assembly includes a bolt (1) having first and second ends and comprising a bolt head (3) at the first end, a first shank portion (4) having a smooth circumferential surface of a first diameter and a second shank portion (5) coaxial with the first shank portion and of a second diameter smaller than the first diameter. At least a part of the second shank portion (5) is externally screw threaded and the first shank portion (4) is positioned between the bolt head (2) and the second shank portion (5). A nut (12) has first and second ends and includes a first bore (15) extending from the first end of the nut and of a diameter greater than the first diameter for fitting over part of the first shank portion (4) of the bolt (2), and, in the region of the second end, a screw threaded bore (17) for screw threaded engagement with the screw threaded second shank portion (5), the screw threaded bore (17) being coaxial with and leading into the first bore (15).
