Abstract:
1. A method of forming a dielectric substrate having a multiturn inductor, the method comprising the steps of: a) obtaining a plurality of layers; b) forming conductive lines on a first group of layers; c) forming conductive vias in a second group of layers; d) forming conductive lines on a third group of layers; e) stacking at least one layer from the second group of layers on at least two layers from the third group of layers; and f) stacking at least two layers from the first group of layers on the at least one layer from the second group of layers wherein the stacking of the first, second and third groups of layers cause the vias in the second group of layers to contact the conductive lines in the first and third groups of layers to form an inductor buried within a dielectric substrate with each turn of the inductor comprising one conductive line from each layer of the first and third groups of layers and the conductive vias from the second group of layers and wherein, with respect to each turn of the inductor, the one conductive lines from each layer of the first group of layers are parallel and in juxtaposition to form a top of the each turn of the inductor and the one conductive lines from each layer of the third group of layers are parallel and in juxtaposition to form a bottom of the each turn of the inductor.
