Methods for creating slanted perpendicular magnetic pole via metal liftoff

摘要

A method in one embodiment includes forming a resist structure above an upper surface of a substrate, wherein a portion of the upper surface of the substrate is a shaping layer, wherein the resist structure has an undercut; depositing a layer of magnetic material above exposed regions of the substrate, wherein a portion of the layer of magnetic material tapers towards the substrate as it approaches the undercut; removing the resist structure; and forming a write pole above the layer of magnetic material. Additional methods are disclosed.
