Abstract:
1. A method for manufacturing a magnetic write head for perpendicular magnetic data recording, the method comprising: providing a substrate; depositing an electrically conductive seed layer over the substrate; depositing a photo resist material; photolithographically exposing and developing the photo resist material to form an opening in the photo resist material; depositing a chemical shrink material; baking the photoresist material to cause a portion of the shrink material to bond with the photo resist material; blanket exposing the photo resist to generate acid for increasing bonding between the chemical shrink material and the photo resist; removing an un-bonded portion of the chemical shrink material leaving the portion of the chemical shrink material that has bonded to the photo resist material; and electroplating a magnetic material into the opening in the photo resist material to from a write pole.
