摘要： One preferred method for use in making a device structure with use of the resist channel shrinking solution includes the steps of forming a first pedestal portion within a channel of a patterned resist; applying a resist channel shrinking solution comprising a resist channel shrinking film and corrosion inhibitors within the channel of the patterned resist; baking the resist channel shrinking solution over the patterned resist to thereby reduce a width of the channel of the patterned resist; removing the resist channel shrinking solution; and forming a second pedestal portion within the reduced-width channel of the patterned resist. Advantageously, the oxide layer and the corrosion inhibitors of the resist channel shrinking solution reduce corrosion in the pedestal during the act of baking the resist channel shrinking solution.

摘要： A method of temporarily protecting an electrically sensitive component from damage due to electrostatic discharge is disclosed. The method includes the steps of defining a first shield that forms a first lead for both a component and a shunt; depositing a conductive material on the first shield to form the component and the shunt; defining an edge of the component and an edge of the shunt together in a single masking step; refilling with insulation adjacent the component and the shunt to their respective edges on the first shield; defining a second shield on both the component and the shunt that forms a second lead for both the component and the shunt to form a shunted assembly that electrically protects the component; lapping the shunted assembly; and removing a portion of the shunted assembly to remove the shunt and form an electrical open for an unshunted assembly.

摘要： A slider for a magnetic disk drive is disclosed which includes a heater circuit structure, and at least one ELG circuit structure where a portion of the ELG circuit structure is removable by lapping. The ELG circuit structure is connected electrically in parallel with the heater circuit structure to a common set of electrical contact pads to produce a measured initial parallel resistance as measured at the common set of electrical contact pads. A modified parallel resistance is calculated to correspond to that of the modified individual resistance of the ELG when lapping operation is completed. The resistance is monitored during lapping operations to signal when the appropriate lapping depth is achieved. Also disclosed is a disk drive having the slider, and a method of fabrication for a slider.

摘要： A process for fabricating sliders where the sliders are held in place during processing by a solid matrix material is described. A thin coating of a release-layer material is applied on the sliders before encapsulation in the matrix material. The release-layer material is polyvinyl alcohol and more preferably high molecular weight polyvinyl alcohol which is highly hydrolyzed. Use of the release-layer of the invention maintains the process resistance while providing the advantage of allowing easier removal of the matrix material after it is no longer needed. The release-layer can be applied to encapsulant materials including epoxies, acrylates, polyimides, silsesquioxanes and others. After the selected fabrication process such as the formation of air-bearing features an appropriate solvent is applied to soften the polyvinyl alcohol film and allow clean debonding of the sliders.

摘要： A method is provided for resetting the magnetization of the pinned and hard biasing layers of a spin valve read head at the row level. In a first embodiment of the invention a first magnetic field is applied substantially perpendicular to the air bearing surface (ABS) at room temperature for setting the magnetic moment of the pinned layer substantially perpendicular to the ABS followed by applying a second magnetic field substantially parallel to the ABS for setting the magnetic moments of the hard biasing layers substantially parallel to the ABS. In a second embodiment of the invention the antiferromagnetic pinning layer is also reset. This is done by heating the pinning layer with a current pulse conducted through the leads to the conductive layers of the spin valve head so that localized heating takes place adjacent the pinning layer as contrasted to ambient heating of the spin valve head. Simultaneous with the localized heating the first magnetic field is applied for orienting the magnetic spins of the pinning layer perpendicular to the ABS and resetting the magnetic moment of the pinned layer perpendicular to the ABS in a single domain state. Subsequently, a second magnetic field is applied for resetting the magnetic moment of the hard biasing layer parallel to the ABS in a single domain state.
