Abstract
A method for constructing a solenoid inductor includes positioning an inner winding substantially around a magnetic core, positioning an outer winding substantially around the inner winding, and using a layered process to perform said positioning the inner and outer windings. The layered process includes processing a first conducting layer as a bottom layer of the outer winding, above processing a first dielectric layer, above processing a second conducting layer as a bottom layer of the inner winding, above processing a second dielectric layer, above processing a magnetic core layer, above processing a third dielectric layer, above processing a third conducting layer as a top layer of the inner winding, above processing a fourth dielectric layer, above processing a fourth conducting layer as a top layer of the outer winding, above processing a fifth dielectric layer, and the inner and outer windings are electrically connected.
