The present invention presents a method for fabricating coil elements for
magnetic write heads. A coil pattern is formed on a substrate using
photolithographic techniques. The substrate is etched using reactive ion
etching, creating a coil-shaped trench in the substrate. Thin film seed
layers are deposited using ion beam deposition. The substrate is
electroplated with metal filling the trenches with metal. The substrate
is chemical mechanical polished to remove excess metal and planarize the
air bearing surface of the write head.
