摘要： Tunneling magnetoresistive (TMR) electrical lapping guides (ELG) are disclosed for use in wafer fabrication of magnetic sensing devices, such as magnetic recording heads using TMR read elements. A TMR ELG includes a TMR stack comprising a first conductive layer, a barrier layer, and a second conductive layer of TMR material. The TMR ELG also includes a first lead and a second lead that connect to conductive pads used for applying a sense current to the TMR ELG in a current in plane (CIP) fashion. The first lead contacts one side of the TMR stack so that the first lead contacts both the first conductive layer and the second conductive layer of the TMR stack. The second lead contacts the other side of the TMR stack so that the second lead contacts both the first conductive layer and the second conductive layer of the TMR stack.

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.
摘要翻译：描述了一种用于制造滑块的方法，其中滑块在由固体基质材料处理期间保持就位。剥离层材料的薄涂层在封装在基质材料中之前施加在滑块上。剥离层材料是聚乙烯醇，更优选高度水解的高分子量聚乙烯醇。本发明的释放层的使用保持了工艺阻力，同时提供了在不再需要基质材料之后容易去除基质材料的优点。释放层可以应用于包括环氧树脂，丙烯酸酯，聚酰亚胺，倍半硅氧烷等的包封材料。在选择的制造方法如形成空气轴承特征之后，施加适当的溶剂以软化聚乙烯醇膜并允许滑块的清洁脱粘。
