The preferred embodiment of the present invention provides a write head having an interlaced conductor coil winding and method of fabrication. The interlaced winding of the present invention may have alternating turns of a first and a second coil. In the preferred embodiment, the side walls of successive coil turns are separated by an ultra thin inorganic insulation which defines the distance between successive turns of the first and second coil. In one method of fabrication, a conductive seed layer is deposited on a generally planar insulative surface, a resist mask is formed on the seed layer, and a conductive material deposited on the exposed seed layer to form the turns of the first coil. The masked portions of the seed layer are removed, after resist mask removal, to electrically isolate the turns of the first coil. The inorganic insulation may be formed in a layer conformal with the first coil. The second coil is formed between the turns of the first coil. A seed layer and mask may be used to facilitate second coil deposition. Etching, or planarization, may be used to electrically isolate the turns of the second coil. A capping layer may be formed over any exposed conductor material to insulate the winding from an upper pole structure or other overlying structure. Embodiments of the present invention may have multiple layers of conductor winding having some conventional, or all interlaced coil structure.
