    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.

    摘要: A writer for high frequency, data storage heads. The writer includes a first magnetic pole upon which a write gap pedestal is formed with an upper pedestal layer of high moment material with a planar upper surface. An electrical coil is formed on the first magnetic pole. A write gap layer is deposited on the upper surface of the upper pedestal layer. The writer includes a second magnetic pole disposed above the first magnetic pole with a magnetic, flat, top pole layer. The second magnetic pole includes a bottom shaper fabricated from high moment material positioned between the coil and the top pole layer. An insulation insert separates the bottom shaper from the upper pedestal layer. The second magnetic pole includes a thin dielectric lamination layer that separates the top pole layer from the bottom shaper to disrupt the path of eddy current in the second magnetic pole.

    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: A method of making an inductive transducer having inorganic nonferromagnetic material disposed in an apex region adjacent to a submicron nonferromagnetic gap in a magnetic core. The inorganic nonferromagnetic apex region can be made by chemical etching of a layer of inorganic nonferromagnetic material, deposition of inorganic nonferromagnetic material through a mask that is then lifted-off, or anisotropic etching of a layer of inorganic nonferromagnetic material that is covered by a hardbaked photoriesist mask.

    摘要: A magnetic head for writing information on a relatively-moving medium includes a first substantially flat soft magnetic pole layer and a second substantially flat pole layer with at least one coil layer between them. The pole layers are magnetically coupled in a core region and spaced by more than one micron from one other. A soft magnetic pedestal adjoins the first pole layer adjacent to a medium-facing surface of the head, and a first high magnetic saturation layer adjoins the pedestal. A second high magnetic saturation layer adjoins the second pole layer. The first high magnetic saturation layer has a first throat height and the second high magnetic saturation layer extends from the medium-facing surface only to a second throat height. The first and second throat heights are within about one and one-half microns from the medium-facing surface and are essentially equal.

    摘要: A magnetic head for writing information on a relatively-moving medium has a pair of substantially flat soft magnetic pole layers separated by a pair of coil layers. A soft magnetic pedestal adjoins the leading pole layer adjacent to a medium-facing surface and is spaced from the second pole layer by a nanoscale nonferromagnetic gap, the pedestal having a layer of high magnetic saturation material that defines a throat height and extends beyond the throat height. A second high magnetic saturation material adjoins the trailing pole layer and either terminates at the throat height to form a second pedestal or extends to reach a magnetic backgap structure that magnetically couples the pole layers. The MR sensor can be located closer than the write transducer to the trailing end of the head to reduce separation between the read transducer and the write transducer.
