摘要： A magnetic write head for data recording having a magnetic write pole with a stepped magnetic shell structure that defines a secondary flare point. The secondary flare point defined by the magnetic shell portion can be more tightly controlled with respect to its distance from the air bearing surface (ABS) of the write head than can a traditional flare point that is photolithographically on the main pole structure. This allows the effective flare point of the write head to be moved much closer to the ABS than would otherwise be possible using currently available tooling and photolithography techniques. The write head may also include a magnetic trailing shield that wraps around the main pole portion. The trailing shield can have a hack edge defining a trailing shield throat height that is either between the secondary flare point or coincident or behind the secondary flare point, depending on design requirements.

摘要： A method for self aligning a lapping guide with a structure of a write pole. A write pole is formed over a substrate and an electrically conductive material lapping guide material is deposited in a location that is removed from the write pole. A mask is then formed over a portion of the write pole and a portion of the electrically conductive material. A material removal process such as reactive ion etching can then be performed to remove a portion of the magnetic material that is not protected by the mask structure. An magnetic material is then electroplated over the write pole with the write pole, with the mask still in place. In this way, the electroplated material has an edge that is self aligned with an edge of the electrically conductive lapping guide material, both being defined by the same mask structure.

摘要： A method and structure for reducing corrosion during the manufacture of perpendicular write heads is disclosed. Auxiliary pole structures (otherwise known as trailing shields and wrap around shields) are susceptible to corrosion due to their iron containing composition and small dimensions. The impact of corrosion can be reduced by utilizing a gap material comprising an upper surface of noble metals, which extends from underneath the auxiliary pole and is exposed to the same corrosive environment during processing. The area of the exposed gap material is limited to optimize corrosion protection.

摘要： Three terminal magnetic sensing devices (TTMs) having base lead layers in-plane with collector substrate materials, and methods of making the same, are disclosed. In one illustrative example, a collector substrate having an elevated region and a recessed region adjacent the elevated region is provided. An insulator layer is formed in full-film over the collector substrate, and a base lead layer is formed in full-film over the insulator layer and in-plane with semiconductor materials of the elevated region. The insulator materials and the base lead materials that are formed over the elevated region are removed. A sensor stack structure having an emitter region and a base region is then formed over the elevated region such that part of the base region is formed over an end of the base lead layer. A base conductive via may be formed to contact base lead materials of the base lead layer at a suitable distance away from the sensor stack structure. Advantageously, the base conductive via formation may occur without causing damage to the sensor stack structure. Also, the base lead layer is formed in the recessed region of the collector substrate prior to the formation of the sensor stack structure such that the TTM may be entirely in-situ manufactured. Furthermore, the trackwidth of the TTM may be defined directly by the elevated region of the collector substrate. The TTM is suitable for incorporation into nanoscale devices which increase areal recording densities, therefore aiding the revolution in magnetic storage.

摘要： A read head has a bottom lead made of material that is relatively polish resistant and a top lead layer that polishes down more easily than the bottom layer. With this structure, when the layers are deposited and then polished down, the top layer recesses away from the sensor (and bottom lead layer) in a controlled fashion, providing an acceptable lead structure that reduces the mismatch between the read head physical read width and magnetic read width.

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.
摘要翻译：一种用于制造磁阻传感器的方法，该传感器允许传感器被构造成具有非常窄且良好控制的轨道宽度。该方法包括在一系列传感器层上沉积一层类似金刚石的碳。然后形成第一掩模以限定传感器，并且执行离子铣削以去除未被第一掩模保护的传感器材料。然后，形成第二掩模，并且在传感器层的厚度上沉积硬偏置层。然后将第二掩模剥离并执行CMP以除去第一掩模结构。由于除传感器正上方的区域以外的所有区域基本上是平面的（由于第二掩模的移除和硬偏置材料的低水平），可以使用快速，温和的CMP来去除第一掩模层，即使第一个掩模很小，如定义非常窄的轨道宽度传感器。
