Abstract: A method for manufacturing a magnetic write head having a stepped trailing shield. The stepped trailing shield is formed by forming a non-magnetic bump over a write pole prior to electroplating a wrap-around magnetic shield. This bump is formed by constructing a mask having an opening configured to define the non-magnetic bump. A magnetic material is then sputter deposited. In order to decrease deposition of the magnetic material on the sides of the mask, a collimator is used to align the deposited material along a plane substantially parallel with an air bearing surface plane. This collimation of the deposited magnetic material greatly facilitates liftoff, and more importantly prevents the formation of fences which would otherwise have to be removed by a harsh, aggressive process.
