Abstract
A writer pole and a method for fabricating a writer pole is disclosed. The method comprises fabricating a conductive seed layer on a gap substrate and then fabricating a nonmagnetic feature on the seed layer where the nonmagnetic feature has a top layer and a plurality of sides. The seed layer and nonmagnetic feature are covered with photoresist. A window is fabricated in the photoresist, exposing a portion of the nonmagnetic feature and a portion of the seed layer, thereby exposing a top portion and a side portion of the nonmagnetic feature and exposing a portion of the seed layer. The portion of the seed layer in the window area is removed from the gap substrate. A pole is fabricated on the top and side portions of the nonmagnetic feature in the window area.
