摘要： A wafer containing integrated circuits having fuses which are selectively blown to trim circuit perimeters. The fuses are located adjacent scribe lanes, and fuse pads are located in the scribe lanes. The integrated circuits are trimmed by selectively energizing the fuse pads to blow selective fuses. When the integrated circuits are severed from the wafer, the fuse pads are severed from the integrated circuits.

摘要： In a method and system for reducing power consumed by a magnetic memory, magnetic memory cells are coupled to a bit line and are associated with a plurality of digit lines. A bit line current is provided in the bit line. Digit currents are provided in parallel in the digit lines at substantially the same time as the bit line current. The digit and bit line currents allow the magnetic memory cells to be written to a plurality of states in parallel.

摘要： A magnetic head includes first and second pole tips separated by a nonmagnetic gap layer. The right side walls of the first and second pole tips are vertically aligned. Similarly, the left side walls of the first and second pole tips are vertically aligned. The side fringing flux is substantially reduced resulting in a magnetic head capable of writing data tracks with well defined boundaries. The fabrication of the magnetic head begins with forming a stack of layers on a substrate. The stack of layers includes a nonmagnetic layer sandwiched between the first pole tip layer and a sacrificial layer which is preferably made of a metal. A protective layer, such as alumina, is then deposited over and around the stack of layers. After planarization and ion milling, the sacrificial layer is exposed. The sacrificial layer is then etched away leaving a volume of space in the protective layer and above the gap layer. An inductive coil with associated dielectric layers are then deposited above the first pole layer. The second pole layer is thereafter deposited over the inductive coil and into the volume of space resulting in the first and second pole tips having vertically aligned side walls.

摘要： An inductive transducer having first and second magnetic pedestals disposed between first and second magnetic pole layers and adjacent to a media-facing surface, the pedestals separated by a submicron, nonmagnetic gap. The first pedestal extends less than the second pedestal from the media-facing surface, defining a short throat height. The second pedestal extends further to provide sufficient area for stitching to the second pole layer. The stitching and the thickness provided by the pedestals allow plural coil layers to be disposed between the pole layers, and the second pedestal, as well as other features, can be defined by high-resolution photolithography. The two coil layers have lower resistance, lower inductance and allow the pole layers to be shorter, improving performance. All or part of either or both of the pedestals may be formed of high magnetic saturation material, further enhancing performance.

摘要： A magnetic head includes pole tips with aligned sidewalls and a low head profile. The aligned sidewalls are formed by depositing a stack of pole tip layers on a substrate. The stack of layers are etched through a common overlying mask. The stack of layers is covered over and around with a protective layer which is then planarized such that the stack of layers is exposed. The protective layer is etched to a predetermined thickness above the substrate, which is thinner than the thickness of the stack of layers. An inductive coil layer is deposited on the etched protective layer and covered with an overlying magnetic yoke layer which is dielectrically separated from the coil layer. The yoke layer thus formed assumes a low profile curvature due to the thin structure of the protective layer on the substrate. As a consequence, the overall stack height of the magnetic head is reduced, thereby reducing the inductance of the overlying yoke layer and further alleviating the step coverage problem of the magnetic head during fabrication.

摘要： A magnetic head includes first and second pole tip layers separated by a nonmagnetic gap layer. The pole tips are made of a high magnetic moment material. The right side walls of the first and second pole tips are vertically aligned with each other. Similarly, the left side walls of the first and second pole tips are vertically aligned with one another. The side fringing flux from one pole tip to another is substantially reduced resulting in a magnetic head capable of writing data tracks with well defined boundaries. The possibility of the pole tips operating in magnetic saturation is reduced because the pole tips, formed of high magnetic moment material, is capable of accommodating high coercive force. The magnetic head can be fabricated as an inverted head or a non-inverted head capable of writing on magnetic media with high coercivity and at a high data transfer rate.
