摘要： An optical switch with a compact form factor includes a multiple-fiber collimator and an angle tuning element for deflecting an optical beam from an input fiber into one of at least two output fibers. The angle tuning element may be provided between a pair of coaxially-aligned collimators, one of which is the multiple-fiber collimator. Alternatively, the angle tuning element may be provided between the multiple-fiber collimator and a reflective surface, so that only one collimator is required and the optical switch may be designed to have its input and output ports on the same side.

摘要： The problem of copper corrosion that occurs in the presence of strong alkaline developing solutions during photo rework has been overcome by protecting all exposed copper bearing surfaces from attack. Two ways of achieving this are described. In the first method, benzotriazole (BTA) is added to the developing solution which is then used in the normal way, developing time being unaffected by this modification. In the second method, the surface that is to receive the photoresist is first given a dip in a solution of BTA, following which the photoresist is immediately applied and processing, including development, proceeds as normal. For both methods the result is the elimination of all copper corrosion during development.

摘要： A non-magnetic conductor material, a magnetic transducer element having formed therein a non-magnetic conductor layer formed of the non-magnetic conductor material and a method for forming a magnetic transducer element having formed therein the non-magnetic conductor layer formed of the non-magnetic conductor material. The non-magnetic conductor material comprises an alloy comprising nickel and at least one non-magnetic conductor metal selected from the group consisting of copper at a weight percent of from about 45 to about 90, zinc at a weight percent of from about 20 to about 75, cadmium at a weight percent of from about 35 to about 85, platinum at a weight percent of from about 55 to about 90 and palladium at a weight percent of from about 75 to about 95. The non-magnetic conductor material contemplates the magnetic transducer element and the method for forming the magnetic transducer element.

摘要： A method for forming a plated layer. There is first provided a substrate. There is then formed over the substrate a masking frame employed for masking frame plating a masking frame plated layer within the masking frame, where the masking frame is fabricated to provide an overhang of an upper portion of the masking frame spaced further from the substrate with respect to a lower portion of the masking frame spaced closer to the substrate. Finally, there is then plated the masking frame plated layer within the masking frame. The method is useful for forming masking frame plated magnetic pole tip stack layers with enhanced planarity dimensional control within magnetic transducer elements.
