Abstract:
A monolithic semiconductor inductive component comprising:a semiconductor substrate which extends primarily in a substrate plane;a first conductive spiral having a first axis and being formed as a sole conductive spiral above a first portion of said substrate so that said first axis is substantially perpendicular to said substrate plane, wherein a current passes through said first conductive spiral in a first spiral direction;a second conductive spiral having a second axis and being formed as a sole conductive spiral above a second portion of said substrate so that said second axis is substantially perpendicular to said substrate plane and substantially parallel to said first axis, wherein said current passes through said second conductive spiral in a second spiral direction opposing said first spiral direction; andan interconnection electrically coupling said first conductive spiral to said second conductive spiral to form a monolithic inductor in which said current produces first magnetic flux lines for said first conductive spiral and second magnetic flux lines for said second conductive spiral, and wherein said first and second magnetic flux lines point in opposing directions and are guided away from said substrate.
