摘要:
A bonding pad structure for an LED includes a first layer of nickel-chromium in contact with the contact face of a gallium arsenide wafer with further layers of either gold, palladium, or both, with palladium being the top layer of the first pad structure laid down by vaporization with a raised structure overlying the first structure by means of plating and including layers of nickel, gold and/or other conducting metal.
摘要:
A layer of chromium is removed from the metalization system on a silicon integrated circuit wafer that also includes copper and aluminum. By electrolytic etching in a sulfuric acid solution containing about 10% by volume water saturated with chromium sulfate, chromium can be removed without excessive removal of copper or aluminum.

摘要:
The invention is directed to techniques for inspecting a circuit board having a surface that includes at least one circuit board component. The apparatus includes a base, and a set of reflective members that includes at least one reflective member. Each reflective member of the set of reflective members is (i) supported by the base and (ii) movable relative to the base to enable that reflective member to move to an angle that reflects light from a respective portion of a circuit board component (e.g., a solder region between the component and the circuit board) in a direction away from the surface of the circuit board when the base rests on the surface of the circuit board. Since the base can rest on the surface of the circuit board, a technician does not need to hold the apparatus.

摘要:
A re-configurable optical waveguide includes an electro-optic substrate and plurality of electrodes above substrate. Electrodes are forming photonic crystal waveguide with photonic crystal periodic structure which has a slab optical waveguide on the top surface of a substrate and also has refractive index variation areas due to electro-optical effect with a different refractive index from that of the core layer of the slab optical waveguide arranged in a lattice array shape at part of the slab optical waveguide. In this case, the refractive index variation areas are formed of the same material as the material constituting the core layer of the slab optical waveguide. The refractive index variation areas are arranged in the lattice array shape on both the sides of an optical waveguide area, where light is propagated. The refractive index of the core layers of the refractive index variation areas is larger than that of the core layer of an area of the refractive index variation area. A plurality of electrodes are placed a field emission array with structure density possibly being higher than 10+8 per square centimeter. Groups of the structures are united in pixels with size a equal to the waveguide's width. Different arrays of pixels form variable shapes and, appropriately, variable waveguides. Thus light propagates in the different directions according the waveguide which is formed. Such a waveguide allows implementation of different optical functions simply by changing the arrangement of the patterns. Arrangement of the patterns is controlled with integrated transistor structure, and with a coupled control circuit.

A surgical instrument (11) comprising a handle (13), a retractor blade (15) and an attachment device (17) to releasably secure the retractor blade to a first end (19) of the handle. The surgical instrument is arranged such that in a first condition the attachment device secures the blade to the handle whereby the blade may rotate relative to the handle, whilst in a second condition the attachment means secures the blade to the handle such that the blade is fixed relative thereto.

An improved rework nozzle includes an open housing which when lowered onto the surface of a board forms a closed cavity. The housing includes venting means which expend air that is input to the cavity, thereby using flow through concepts to maintain a uniform temperature in the cavity. The housing also positioning mechanisms for both aligning a the housing and a captive integrated circuit to a desired footprint on the circuit board, and for limiting movement of the integrated circuit during rework.
