    摘要: Methods for forming write heads. One method includes forming a mask layer above a pole tip layer; forming a layer of resist above the mask layer; patterning the resist; removing portions of the mask layer not covered by the patterned resist; shaping a pole tip from the pole tip layer; depositing a layer of dielectric material above the pole tip and flux shaping layer, wherein the layer of dielectric material extends about adjacent to the mask layer; depositing a stop layer over the dielectric material, the stop layer abutting the mask layer; and polishing for forming a substantially planar upper surface comprising the mask layer and stop layer. Another method includes depositing a layer of dielectric material at least adjacent the pole tip, wherein the layer of dielectric material extends about adjacent to the mask layer. A further method includes forming dishing in the pole tip.

    摘要: The magnetic head includes a second magnetic shield that is fabricated in a deposition process. The present invention therefore does not require the deposition of the electrically conductive seed layer. In a preferred embodiment, the deposited second magnetic shield is comprised of cobalt zirconium tantalum (CZT). Because the CZT material is relatively soft, it is preferably deposited within an opening formed in a relatively hard RIEable material such as Ta2O5, SiO2, Si3N3, and SiOxNy, such that a subsequent chemical mechanical polishing (CMP) step can be conducted down to the surface of the relatively hard layer.

    摘要: A method for manufacturing a manufacturing a magnetoresistive sensor that allows the sensor to be constructed with a very narrow and well controlled track width. The method includes depositing a layer of diamond like carbon over a series of sensor layers. A first mask is then formed to define a sensor, and an ion milling is performed to remove sensor material not protected by the first mask. Then, a second mask is formed, and a hard bias layer is deposited to the thickness of the sensor layers. The second mask is then lifted off and a CMP is performed to remove the first mask structure. Because all areas other than the area directly over the sensor are substantially planar a quick, gentle CMP can be used to remove the first mask layer even if the first mask is small, such as for definition of a very narrow track-width sensor.

    摘要: A method for manufacturing a magnetoresistive sensor that results in the sensor having a very flat top magnetic shield. The process involves depositing a plurality of sensor layers and then depositing a thin high density carbon CMP stop layer over the sensor layers and forming a mask over the CMP stop layer. An ion milling is performed to define the sensor. Then a thin insulating layer and magnetic hard bias layer are deposited. A chemical mechanical polishing is performed to remove the mask and a reactive ion etching is performed to remove the remaining carbon CMP stop layer. Because the CMP stop layer is very dense and hard, it can be made very thin. This means that when it is removed by reactive ion etching, there is very little notching over the sensor, thereby allowing the upper shield to be very thin.

    摘要: Embodiments herein generally relate to TMR readers and methods for their manufacture. The embodiments discussed herein disclose TMR readers that utilize a structure that avoids use of the DLC layer over the sensor structure and over the hard bias layer. The capping structure over the sensor structure functions as both a protective layer for the sensor structure and a CMP stop layer. The hard bias capping structure functions as both a protective structure for the hard bias layer and as a CMP stop layer. The capping structures that are free of DLC reduce the formation of notches in the second shield layer so that second shield layer is substantially flat.
