    摘要： A method of manufacturing a write pole that prevents P2 pedestal consumption during ion milling removal of coil and pole seed layers. The write head can be constructed by forming a first pole and then forming a magnetic pedestal (P2) over the first pole. A protective layer of, for example, alumina is deposited over a portion of the pedestal in the pole tip region, leaving a portion of the pedestal uncovered in the flare region. A coil seed layer can then be deposited and a coil formed. When the coil seed layer is removed, such as by ion milling, the pole tip region of the pedestal is protected from the ion milling by the protective layer. Similarly, a top pole can be deposited by first depositing an electrically conductive, magnetic seed layer and then plating the top pole. When the top pole seed layer is removed by ion milling, the pole tip region of the pedestal is protected from removal by the protective layer.

    摘要翻译： 一种制造写入极的方法，该写入极在离子铣除去线圈和极种子层期间防止P2基座消耗。 写头可以通过形成第一极，然后在第一极上形成磁性基座（P2）来构造。 例如氧化铝的保护层沉积在极尖区域中的基座的一部分上，使基座的一部分露出在扩口区域中。 然后可以沉积线圈种子层并形成线圈。 当线圈种子层被去除时，例如通过离子铣削，底座的极尖区域被保护层防止离子铣削。 类似地，可以通过首先沉积导电的磁性种子​​层然后电镀顶极来沉积顶极。 当通过离子研磨去除顶极种子层时，保护基座的极尖区域被保护层除去。

    摘要： During fabrication of a write head via holes are first opened in a gap layer, followed by formation of seed layers instead of the other way around. Moreover a first seed layer is formed, and without the first seed layer being used a second seed layer is formed. The second seed layer (which is the topmost layer) is used in plating to form coils (e.g. of copper) for the write head. After coil formation, the first seed layer is used for plating to form vias (e.g. of NiFe). The two seed layers may be formed in a single operation by using two different targets in a vacuum deposition chamber. Moreover, a single insulation layer is sufficient to insulate and protect all plated elements, regardless of whether they are formed by use of the first seed layer or the second seed layer.
