Abstract
A process for producing single-layer or multi-layer microcoils or microcoil arrays that optionally have a magnetic core area to increase the coil inductance and to guide the magnetic flux. In this process, plastic films (e.g., made of polyimide or polyester), are applied using pressure and heat to serve as the insulation layers. This eliminates the need for curing the insulation and expensive leveling operations.
