Patent ID: 8444866

Claim:
A method for fabricating a magnetic transducer having an intermediate layer, the method comprising: providing a trench in the intermediate layer, the trench having a profile and a location corresponding to a pole of the magnetic transducer, the intermediate layer being nonmagnetic; providing a first nonmagnetic gap layer, at least a portion of the first nonmagnetic gap layer residing in the trench; providing the pole including at least one magnetic material, at least a portion of the pole residing in the trench and on the portion of the first nonmagnetic layer; removing at least a portion of the intermediate layer adjacent to the pole; providing a second nonmagnetic gap layer after the portion of the intermediate layer is removed, the second nonmagnetic gap layer being thicker than the first nonmagnetic gap layer, a portion of the second nonmagnetic layer and a portion of the first nonmagnetic layer adjacent to the pole forming a side gap; providing a side shield; providing a gap on the pole, the side gap, and a portion of the side shield; and providing a top shield, wherein the step of providing the second nonmagnetic gap layer further includes; atomic layer depositing an insulating layer; and chemical vapor depositing an additional layer of Ru.
