Abstract:
A method and system for providing a PMR transducer including an intermediate layer. The method and system include providing a hard mask layer on the intermediate layer. The hard mask layer is for a reactive ion etch of the intermediate layer. The method and system also include providing a bottom antireflective coating (BARC) layer on the hard mask layer. The BARC layer is also a masking layer for the hard mask layer. The method and system also include forming a trench in the intermediate layer using at least one reactive ion etch (RIE). The trench has a bottom and a top wider than the bottom. The method and system also include providing a PMR pole. At least a portion of the PMR pole resides in the trench.
