Methods for creating a stepped perpendicular magnetic pole via milling and/or metal liftoff

A method in one embodiment includes forming a layer of a nonmagnetic material above an upper surface of a substrate; forming a resist structure above the layer of nonmagnetic material, wherein the resist structure has an undercut; removing a portion of the layer of nonmagnetic material not covered b...

More Information
Summary:A method in one embodiment includes forming a layer of a nonmagnetic material above an upper surface of a substrate; forming a resist structure above the layer of nonmagnetic material, wherein the resist structure has an undercut; removing a portion of the layer of nonmagnetic material not covered by the resist structure; depositing a layer of magnetic material above the substrate adjacent a remaining portion of the layer of nonmagnetic material such that at least portions of the layer of magnetic material and the remaining portion of the layer of nonmagnetic material lie in a common plane; removing the resist structure; and forming a write pole above the layer of magnetic material and the remaining portion of the layer of nonmagnetic material. Additional methods are also presented.
