Patent ID: 7395595

Claim:
A method for manufacturing P 3 layer of a perpendicular magnetic write head comprising: forming a laminated layer; forming an alumina layer on top of the laminated layer; depositing a conductive layer onto the laminated layer; forming a plating frame made of two plating frame layers formed on top of the conductive layer, said plating frame layers being separated from each other by a trench defined by an initial track width; shrinking the trench; plating a platable material into a portion of the trench; stripping the plating frame layers leaving the plated material; removing the conductive layer except the conductive layer formed below the plated material defined by a first layer ( 622 ); removing the alumina layer except the alumina layer formed below the first layer defined by a second layer ( 624 ); while removing the alumina layer, removing the laminated layer except the laminated layer formed below the second layer; and patterning the laminated layer formed below the plated trench further patterning the removed laminated layer formed below the second layer.
