Abstract:
1. A method for manufacturing a magnetic write head, comprising: forming a magnetic write pole over a substrate; depositing an electrically conductive seed layer; forming a first photoresist mask having an opening and having a thickness; depositing shrink material, the shrink material having a thickness that is less than the thickness of the first photoresist mask; heating the first photoresist mask and shrink material to form the opening in the first photoresist mask with a bulbous side; removing the shrink material; electroplating a non-magnetic material into the opening in the first photoresist mask, the bulbous side of the first photoresist mask forming the electroplated non-magnetic material with a tapered edge; removing the first photoresist mask; forming a second photoresist mask having an opening configured to define a trailing magnetic shield; and electroplating a magnetic material into the opening in the second photoresist mask to from the trailing magnetic shield, at least a portion of the trailing magnetic shield being formed over the tapered edge of the non-magnetic material.
