  • Patent number: 7263762
    Abstract: A method for reducing plated pole height loss in the formation of a write pole for a magnetic write head is disclosed. The method includes forming a conductive layer on a thin film substrate, forming a photoresist layer on the conductive layer and forming a trench in the photoresist layer. A thick seed layer is then placed on the trench and on the photoresist layer surface using a collimator. Moreover, the process includes plating while applying a voltage to the thin film substrate where the electrically isolated seed layer is removed and the trench is filled with plating material, removing the photoresist layer, and removing the exposed portions of the conductive layer on the thin film substrate.
