Abstract: A method for finishing a pole tip trimmed read/write heat that includes a substrate with a pole tip structure having a shield, a shield/pole, and an outer pole. A gap region separates the pole and the shield/pole. First, pole tip trimming is performed to the read/write head to remove matter from the shield/pole, the pole, and the gap region. This defines a bridge composed of inward-facing extensions of the pole and shield/pole interconnected by an intervening region. This bridge separates recessed “trenches,” each formed by removing a contiguous mass from the shield/pole, the gap region, and the pole. Next, an overlayer is applied over the pole tip structure, filling the recessed trenches. The coated structure is then trimmed to remove all coating material overlying the shield/pole and pole. Trimming is continued to additionally remove a top layer of the protrusions of the pole and shield/pole to remove any rounded edges created by pole tip patterning, resulting in a more distinct write head.

Abstract: Twist pins having bulges are fabricated from helically coiled stranded wire. Wire is advanced from a source such as a spool to create slack wire configuration, and wire is then advanced from the slack wire configuration to a position where each bulge is formed. Each bulge is formed by gripping the wire in two spaced apart locations and rotating the wire in an anti-helical direction in a single continuous relative revolution to untwist the strands and form the bulge. The wire is thereafter advanced to the position of the next bulge or the position where the wire will be severed to release the fabricated twist pin. The severed fabricated twist pin is conveyed through a flow of gas in a delivery tube into a receptacle of a cassette where the twist pin is stored until used. The cassette is automatically moved to position an occupied receptacle to receive each newly fabricated twist pin.

Abstract: A module or assembly is formed by interposing a polymer between a carrier and a semiconductor device to be secured to the carrier. The polymer has ionized metallic particles suspended in it. Before setting or curing the polymer, the module is exposed to an electric field which induces migration of the metallic particles to the opposing pads of the carrier and semiconductor device. Such migration ultimately forms metal dendrites extending between mating pad pairs. The dendrites establish a metallurgical bond and conductive paths between the carrier and the overlying semiconductor device. When the polymer is subsequently set, the carrier and device are not only adhered to each other, but the dendrite connections are fixed and structurally reinforced to provide the needed electrically conductive paths.
