    • A method for manufacturing a magnetic write head having a write pole with a tapered, stepped trailing edge. The method includes depositing a magnetic write pole material over a substrate, and then forming a magnetic step structure over the magnetic write pole material. A mask structure is then formed, which includes a multilayer hard mask formed over the magnetic write pole material and the magnetic step structure. An ion milling process is then performed to remove a portion of the write pole material to define a write pole. A non-magnetic material can be deposited and ion milling performed to form non-magnetic side gap layer at the sides of the write pole. A multi-step reactive ion milling process can then be performed to remove the remaining hard mask from over the write pole.
    • 一种用于制造磁头的方法,该写磁头具有带锥形的阶梯式后缘的写极。 该方法包括将磁性写入磁极材料沉积在衬底上,然后在磁性写入磁极材料上形成磁性阶梯结构。 然后形成掩模结构,其包括形成在磁性写入磁极材料和磁性步骤结构之上的多层硬掩模。 然后执行离子铣削工艺以去除写入极材料的一部分以限定写入极。 可以沉积非磁性材料并进行离子铣削以在写入极的两侧形成非磁性侧隙层。 然后可以执行多步反应离子研磨过程,以从写极上去除剩余的硬掩模。

    • A method for manufacturing a magnetic write head that avoids the challenges associated with the formation of fence structures during write pole definition. A magnetic write pole material is deposited. A mask structure is deposited over the magnetic write pole material. The mask structure includes a first hard mask, a marker layer, a physically robust, inorganic RIEable image transfer layer, a second hard mask structure over the image transfer layer and a photoresist layer over the second hard mask. A reactive ion etching process can be used to transfer the image of the photoresist mask and second hard mask layer onto the image transfer layer. An ion milling is performed to define the write pole. A layer of non-magnetic material such as alumina is deposited. An ion milling is performed until the marker layer has been reached, and another reactive ion etching is performed to remove the remaining hard mask.
    • 一种用于制造写磁头的磁头的方法,其避免了写磁极定义期间与栅栏结构的形成有关的挑战。 沉积磁性写入极材料。 掩模结构沉积在磁性写入极材料上。 掩模结构包括第一硬掩模,标记层,物理上坚固的无机RIEable图像转印层,图像转印层上方的第二硬掩模结构和在第二硬掩模上的光致抗蚀剂层。 可以使用反应离子蚀刻工艺将光致抗蚀剂掩模和第二硬掩模层的图像转印到图像转印层上。 执行离子铣削以限定写入极。 沉积一层非磁性材料如氧化铝。 进行离子研磨直到达到标记层,并执行另一反应离子蚀刻以除去剩余的硬掩模。
