ABSTRACT:
A lift-off method for forming write pole of a magnetic write head and write pole formed thereby is disclosed. A write pole including a hard mask on a top portion of the write pole is formed. A layer of material for reinforcing sidewall fencing of the write pole is deposited. Portions of the layer of material on top of the write pole are removed while the layer of material at the sidewall fencing is left to provide support to the sidewall fencing.
