Methods for fabricating thin film magnetic head coil structures are disclosed. The methods disclose deposition of a first thick seed layer, followed by deposition of an ultra-thin second seed layer. Coil structures having sub-micron pitch and high aspect ratios are deposited on the second ultra-thin seed layer, which is removed from between the coil windings via an isotropic etch process such as wet etching or RIE. Subsequent to selective removal of the ultra-thin second seed layer, the first thick seed layer is utilized to deposit pole and backgap structures, eliminating the need to deposit (and remove) a subsequent seed layer on the coil structure.
