摘要： A read/write head and method of making the same are used in a data storage system, such as a disk drive, for perpendicular magnetic recording of data. The head employs a two-layer pole design with a main pole made of sputtered high moment magnetic material, and an adjunct pole made of electroplated soft magnetic film. The main pole is used to write data onto the medium, and is formed over the write coil. The adjunct pole is substantially recessed from the air bearing surface and is formed over the main pole. The present head design significantly enhances the magnetic write field, and substantially reduces side-writing that result in accidental erasure of data in adjacent tracks on the magnetic recording medium.

摘要： In one aspect, a laminated structure including a first plurality of layers containing primarily-iron FeCoN interleaved with a second plurality of layers containing primarily iron FeNi is disclosed. The structure has an easy axis of magnetization and a hard axis of magnetization, has a magnetic saturation of at least about twenty-three-thousand Gauss, and has a magnetic coercivity measured substantially along its hard axis of magnetization that is less than two Oersted. Additional elements can be added in minority concentrations to form primarily-iron FeCoN layers with increased resistivity. The laminated structure has applicability in various fields in which high saturation magnetization, magnetically soft materials are advantageous, particularly for inductive heads.

摘要： An inductive write head structure incorporating a high moment film in conjunction with at least one pole (e.g., the bottom pole) for use with magnetic storage media and a process for producing the same in which a lift-off photoresist mask is used prior to the deposition of the high moment sputtered film. Following the lift-off process, the high moment film remains on the bottom pole (“P1”) pedestal (in the case of a PDZT type write head) or on the P1 itself (in the case of a Stitched Pole write head). The edge of the lift-off sputtered film is then covered by cured photoresist insulation which is placed at a distance away from the air bearing surface (“ABS”). The coverage of insulation at the edge of the sputtered film is desirable in order to avoid forming a topographic step which may have undesired consequences in the subsequent top pole formation processes.

摘要： Present invention provides enabling techniques of integrating novel nanotube elements into semiconductor devices, particularly in transistors, as gate channels or/and as interconnects. This is done in a series of process steps, which consist of fabricating magnetic-core-containing nanotubes of selected size (diameter and length), filtration of nanotube powders, preparing nanotube precursor in aqueous chemicals to form colloidal solutions of proper concentration, dispersing nanotube-containing solutions onto wafer surface, and finally positioning nanotubes at desired locations by magnetic means to complete nanotube device structure. The key to this invention is to provide miniature nanotubes with tangible physical properties, in this case, magnetic properties, so that they can be aligned, filtered, and precisely directed to desired locations for device application. Such processes enable nanotubes to be compatible with typical semiconductor wafer processing technologies.

摘要： Present invention provides enabling methods of integrating novel nanotube elements into semiconductor devices, such as transistor containing electronic device. This is done in a series of process steps, which consist of attaching magnetic nanoparticles to nanotubes, tailoring magnetic nanotubes of selected size (diameter and length), filtration of nanotube to pre-determined sizes, preparing nanotube precursor in aqueous chemicals to form colloidal solutions of proper concentration, dispersing nanotube-containing solutions onto wafer surface, and finally positioning nanotubes at desired locations by magnetically assisted assembly to complete nanotube device structure. The key to this invention is to provide miniature nanotubes with tangible physical properties, in this case, magnetic properties, so that they can be aligned, filtered, and precisely directed to desired locations for device application. Such processes enable nanotubes to be compatible with typical semiconductor wafer processing technologies.
