Abstract:
A method of fabricating a coil structure for use in a writer portion of a recording head, the method comprising:fabricating a first seed layer on a bottom insulating layer;fabricating a first plurality of insulating barriers spatially positioned on the first seed layer, wherein the step of fabricating a first plurality of insulating barriers further comprises:fabricating a first pattern coil on the first seed layer, the first pattern coil leaving an exposed first seed layer not covered by the first pattern coil;enhancing a thickness of the exposed first seed layer;isotropically eroding the first pattern coil;removing the enhanced thickness of the exposed first seed layer;fabricating a mask deposition;removing a portion of the mask deposition positioned above the first pattern coil and the exposed first seed layer;stripping the first pattern coil, thereby exposing the first plurality of insulating barriers; andfabricating a first coil conductor and a second coil conductor between the first plurality of insulating barriers such that the first coil conductor and the second coil conductor are alternately positioned between the plurality of first insulating barriers.
