摘要： Methods for creating a write head by forming a bump after the top pole is formed are provided. In one embodiment, a bottom pole is created out of a first layer. A non-magnetic gap material is applied to the surface of the wafer. A top pole is created out of a second layer. After creating the top pole, a bump is created. The bump is used to protect at least a portion of the first layer while etching to create a stray flux absorber.

摘要： A multi-step process for notching the P1 pole of the write head element of a magnetic head. In a first step following the fabrication of the P2 pole tip, a layer of protective material is deposited on the approximately vertical side surfaces of the P2 pole tip. Thereafter, a first ion milling step, utilizing a species such as argon, is performed to mill through the write gap layer and to notch into the P1 pole layer therebelow. The removal of redeposited material from the side surfaces of the P2 pole tip is thereafter accomplished and the protective material formed on the side surfaces of the P2 pole tip protects the P2 pole tip during the redeposition clean up step. Thereafter, the protective material is removed from the side surfaces of the P2 pole tip, and a second ion milling step is performed to further notch the P1 pole material.

摘要： A method for manufacturing a magnetic write head for perpendicular magnetic recording. The method includes forming a write pole, and then depositing a refill layer. A mask structure can be formed over the writ pole and refill layer, the mask structure being configured to define a stitched pole. An ion milling or reactive ion milling can then be performed to remove portions of the refill layer that are not protected by the mask structure. Then a magnetic material can be deposited to form a stitched write pole that defines a secondary flare point. The stitched pole can also be self aligned with an electrical lapping guide in order to accurately locate the front edge of the secondary flare point relative to the air bearing surface of the write head.

摘要： A method for manufacturing a magnetic write head for perpendicular magnetic recording. The method allows the write head to be formed with a write pole having a concave trailing edge. The method further allows the amount of concavity of the trailing edge to be accurately and carefully controlled both within a wafer and between wafers. A write pole is formed using a mask that includes a hard mask, a RIEable layer and an endpoint detection layer. A layer of non-magnetic material (ALD layer) is deposited, and then, an ion milling process is used to remove a portion of the ALD layer disposed over the write pole and mask. A reactive ion etch process is performed to remove the RIEable layer leaving the ALD layer to form non-magnetic side walls with upper portions that extend above the write pole. Another ion milling is then performed, preferably at an angle relative to normal, such that shadowing from the upper portions of the non-magnetic side walls causes the ion milling to form the write pole with a concave trailing edge.

摘要： An optical lapping guide for determining an amount of lapping performed on a row of sliders in a process for manufacturing sliders for magnetic data recording. The optical lapping guide is constructed with a front edge that is at an angle with respect to an air bearing surface plane ABS plane, such that a portion of the lapping guides is in front of the ABS and portion of the lapping guide is behind the ABS. As lapping progresses, an increasing amount of the lapping guide will be exposed at the ABS and visible for inspection. Therefore, after a lapping process has been performed, the optical lapping guide can be inspected to determine the amount of material removed by lapping. The greater the amount of the lapping guide that is exposed and visible, the greater the amount of material removed by lapping.

摘要： A method for manufacturing a write pole for a perpendicular magnetic write head. The method includes forming a mask structure over a full film layer of magnetic write pole material. A layer of hard mask material such as conformally deposited alumina is then deposited full film over the mask and write pole material. An ion mill, such as in an Ar or CHF3 chemistry is then used to preferentially remove horizontally disposed portions of the alumina layer (hard mask layer), thereby forming vertical hard mask walls at the sides of the mask structure. An ion mill is then used to form the write pole, with the alumna side walls providing excellent masking for forming well defined write pole edges. A relatively gentle clean up process can then be performed to remove the remaining mask material and side walls. The use of the alumina side walls eliminated the need to use an alumina hard mask that extends over the entire top of the write pole, Because of this, after forming the write pole, a relatively gentle clean up such as TMAH etch and NMP can be used to remove the remaining mask and alumina walls from the write pole.
