摘要： An inductive write head structure incorporating a high moment film in conjunction with at least one pole (e.g., the bottom pole) for use with magnetic storage media and a process for producing the same in which a lift-off photoresist mask is used prior to the deposition of the high moment sputtered film. Following the lift-off process, the high moment film remains on the bottom pole (“P1”) pedestal (in the case of a PDZT type write head) or on the P1 itself (in the case of a Stitched Pole write head). The edge of the lift-off sputtered film is then covered by cured photoresist insulation which is placed at a distance away from the air bearing surface (“ABS”). The coverage of insulation at the edge of the sputtered film is desirable in order to avoid forming a topographic step which may have undesired consequences in the subsequent top pole formation processes.
摘要翻译：结合至少一个极（例如，底极）与磁存储介质一起使用的高力矩膜的感应写头结构及其制造方法，其中在剥离光刻胶掩模之前使用剥离光致抗蚀剂掩模沉积高速溅射膜。在剥离过程之后，高力矩胶片保留在底极（“P1”）底座上（在PDZT型写入头的情况下）或P1本身（在缝合杆写入头的情况下）。然后，剥离溅射膜的边缘被固定的光致抗蚀剂绝缘体覆盖，该固化的光致抗蚀剂绝缘体被放置在远离空气支承表面（“ABS”）的一定距离处。在溅射膜的边缘处的绝缘层的覆盖是期望的，以避免形成在随后的顶极形成过程中可能具有不期望的后果的地形步骤。

摘要： The present disclosure describes a method for manufacturing a full wraparound shield damascene write head through the implementation of a three layered (tri-layered) hard mask. According to an embodiment of the invention, the various layers of hard mask are used for different purposes during the formation of a write head. The wraparound shield head of the present invention exhibits improved physical characteristics that further result in improved performance characteristics. Use of the hard mask layers according to the present invention allows for use of manufacturing processes that can be more closely controlled than those processes used in other processes. For example, smaller dimension lithographic techniques can be used. Also, reliance on certain CMP processes is not necessary where the use of CMP processes is not as well-controlled as deposition or lithographic techniques as is possible using the present invention.
