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 also includes a non-magnetic spacer layer formed over the magnetic shell structure and a trailing magnetic shield, a portion of which is formed over the non-magnetic spacer.

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 for making a patterned-media magnetic recording disk uses nano-imprint lithography (NIL) for patterning a resist layer over the magnetic recording layer. A hard mask layer is located above the magnetic recording layer and an etch stop layer is located above the hard mask layer and below the resist layer. Residual resist material in the recesses of the patterned resist layer is removed by reactive ion etching (RIE) to expose the underlying etch stop layer. The etch stop material in the recesses is then removed by RIE to expose regions of the hard mask layer. A reactive ion milling (RIM) process removes the exposed hard mask material. The RIM process causes no undercutting of the unexposed hard mask material, which allows the very small critical dimensions of the patterned-media disk to be reliably achieved when ion milling is subsequently performed through the hard mask that has been patterned by the RIM process.
摘要翻译：用于制造图案介质磁记录盘的方法使用纳米压印光刻（NIL）来在磁记录层上图形化抗蚀剂层。硬掩模层位于磁记录层上方，并且蚀刻停止层位于硬掩模层之上和抗蚀剂层下方。通过反应离子蚀刻（RIE）去除图案化抗蚀剂层的凹陷中的残留抗蚀剂材料以暴露下面的蚀刻停止层。然后通过RIE去除凹槽中的蚀刻停止材料以暴露硬掩模层的区域。反应离子研磨（RIM）工艺去除了暴露的硬掩模材料。 RIM工艺不会导致未曝光的硬掩模材料的底切，这允许当通过已经通过RIM工艺图案化的硬掩模进行离子铣削时，可靠地实现图案化介质盘的非常小的临界尺寸。

摘要： An integrated circuit has a doped silicon semiconductor with regions of insulators and bare silicon. The bare silicon regions are isolated from other bare silicon regions. A semiconductor device on the doped silicon semiconductor has at least two electrical connections to form regions of patterned metal. A metal is electroplated directly on each of the regions of patterned metal to form plated connections without a seed layer. A self-aligned silicide is located under each plated connection, formed by annealing, for the regions of plated metal on bare silicon.
