Patent ID: 8563146

Claim:
A method for fabricating a pole in a magnetic transducer having air-bearing surface (ABS), the method comprising: providing an underlayer having a first region, a second region, and a bevel connecting the first region and the second region, the first region having a first thickness and being proximate to the ABS, the second region having a second thickness less than the first thickness and being distal from the ABS; depositing an intermediate layer, the intermediate layer being substantially conformal with the underlayer; providing a hard mask layer on the intermediate layer, the hard mask layer having a top surface substantially perpendicular to the ABS; removing a portion of the hard mask layer and the intermediate layer to provide a trench therein, the trench having a bottom surface and sidewalls having a first angle and a second angle, the first angle being between the bottom surface and the intermediate layer, the second angle corresponding to the hard mask layer; providing a pole, at least a portion of the pole residing in the trench, the pole having a pole tip proximate to the ABS, a yoke distal from the ABS, and a bottom bevel corresponding to the bevel in the underlayer, at least the yoke including a plurality of sidewalls having a plurality of sidewall angles corresponding to the first angle and the second angle.
