Abstract
A method for fabricating an integrated coil-on-keeper assembly for use in a magnetic circuit to actuate a microactuator. The assembly is formed on a keeper substrate by patterning an insulator layer, plating at least one coil layer and patterning another insulator layer on top of each coil layer. The keeper substrate is etched to form the top keeper of the coil-on-keeper assembly.
