Abstract:
A method for fabricating a magnetic head comprising the steps of:fabricating a read head upon a substrate; fabricating a P1 pole upon said read head; fabricating an insulation layer upon said P1 pole; fabricating an RIE etchable dielectric material layer upon said insulation layer; simultaneously fabricating trenches within said dielectric material layer, including a P2 pole tip trench, an induction coil trench and a back gap piece trench; simultaneously fabricating a P2 pole tip within said P2 pole tip trench and a back gap piece within said back gap piece trench, such that said back gap piece is magnetically interconnected with said P1 pole; fabricating an induction coil within said induction coil trench; fabricating a second insulation layer upon said induction coil; fabricating a P2 pole yoke above said second insulation layer in magnetic interconnection with said P2 pole tip and said back gap piece; fabricating an encapsulation layer above said P2 pole yoke.
