    摘要: An integrated inductive write, magnetoresistive (MR) read thin film magnetic head comprising an open magnetic yoke having outside legs each having a winding thereon and a central leg having an opening across which the MR element is coupled. The outer legs are overlapped at one end to form confronting pole pieces having a transducing gap between the pole pieces, and the central leg is positioned between the pole pieces at one end and joined with the outer legs at the other end to form a symmetrical magnetic yoke structure. The windings are wound in a direction so that the flux produced by equally energizing the windings is equal and opposite in each of the outside legs, is additive at the transducing gap between the pole pieces, and produces no net flux through the central leg.

    摘要: Improved adhesion of electroless metal deposited on an organic dielectric layer with phase separated morphology is accomplished by the spontaneous formation of a morphologically and topographically rough surface. In one embodiment a ternary solution of a polar solvent and two polymer precursors of the same polymer which are separable in two phases of different order are cast in film on a substrate and heated to form two phases of different order to spontaneously produce a rough surface. Upon exposure to an alkaline solution, one phase is etched at a faster rate than the other. Seeding and electroless deposition of a metal on the rough surface results in improved adhesion of the metal to the dielectric layer. In a second embodiment a quaternary solution of a polar solvent, a seeding agent, two polymer precursors of the same polymer which are separable in two phases of different order are cast in a thin film on a substrate and heated to form three phases. Upon curing the precursors there is surface roughening as a result of phase separation. Upon exposure to alkaline solution there is etching of one of the polymer phases at a faster rate and simultaneous opening of the seeding colloid. The rough surface is overcoated with a photoresist, exposed and developed. Subsequent electroless metal deposition results in improved metal to dielectric layer adhesion. The method is applicable to selective deposition of electroless copper onto a polyimide layer.

    摘要: A method of patterning magnetic devices and sensors by double etching, which includes forming a layer of dielectric on a substrate; depositing a thin adhesion layer and a thin seed layer; applying a thin resist frame to pattern a structure; cleaning the metal surface to prepare for plating; electroplating to fill up the structure and the uncovered field area, which uses a paddle cell with a permanent magnet providing magnetic field to induce magnetic orientation; stripping the resist frame; etching the seed layer/adhesion layer exposed below the resist frame down to the dielectric surface; etching the rest of magnetic materials and the seed layer using electrolytic etching in the field; etching the adhesion layer in the field, and repeating the steps for building structures with multiple levels.

    摘要: The present invention is related to a method for forming vertical conductive structures by electroplating. Specifically, a template structure is first formed, which includes a substrate, a discrete metal contact pad located on the substrate surface, an inter-level dielectric (ILD) layer over both the discrete metal contact pad and the substrate, and a metal via structure extending through the ILD layer onto the discrete metal contact pad. Next, a vertical via is formed in the template structure, which extends through the ILD layer onto the discrete metal contact pad. A vertical conductive structure is then formed in the vertical via by electroplating, which is conducted by applying an electroplating current to the discrete metal contact pad through the metal via structure. Preferably, the template structure comprises multiple discrete metal contact pads, multiple metal via structures, and multiple vertical vias for formation of multiple vertical conductive structures.
