Patent ID: 8760807

Claim:
A method for fabricating a magnetic transducer having an air-bearing surface location (ABS location) corresponding to an air-bearing surface (ABS), the method comprising: providing an etch stop layer; providing a nonmagnetic etchable layer on the etch stop layer; providing a side shield layer residing between the ABS location and the etch stop layer and between the ABS location and the etchable layer; providing a pole trench in the side shield layer and the etchable layer, the pole trench having a pole tip region and a yoke region wider and deeper than the pole tip region, the pole tip region residing in the side shield layer, the yoke region residing in the etchable layer; providing a nonmagnetic side gap layer, at least a portion of the nonmagnetic side gap layer residing in the pole trench, a remaining portion of the pole trench having a location and profile for a pole; forming the pole, at least a portion of the pole residing in the remaining portion of the pole trench; providing a write gap, at least a portion of the write gap being on the pole; and providing a trailing shield, at least a portion of the trailing shield being on the write gap.
