Abstract
In one embodiment, a method includes forming a conducting material above an insulating film, applying a mask to portions of the conducting material in a shape of a TFC structure, removing exposed portions of the conducting material to form the TFC structure, depositing an insulating film above the TFC structure, and planarizing the insulating film to form a planar upper surface of the insulating film. In another embodiment, a magnetic head includes a TFC structure positioned between insulating films and a magnetic element positioned above the TFC structure, the TFC structure configured for providing localized thermal protrusion of the magnetic head on a media facing surface thereof, wherein an upper surface of an upper of the insulating films is planar, the magnetic element includes at least one of a main magnetic pole and a read sensor, and the TFC structure is configured for providing thermal protrusion of the magnetic element.
