Patent ID: 8441332

Claim:
An inter-helix inductor device, comprising: a multi-layered dielectric substrate having a first surface and a second surface; a first terminal disposed on the first surface of the multi-layered dielectric substrate; a second terminal disposed on the first surface of the multi-layered dielectric substrate, wherein the second terminal is adjacent to the first terminal; a clockwise winding coil with one end on the first surface connecting to the first terminal having at least one winding turn through the multi-layered dielectric substrate, wherein another end of the clockwise winding coil on the second surface connecting to a third interconnection; and a counter clockwise winding coil with one end on the second surface connecting to the second terminal through a second interconnection having at least one winding turn through the multi-layered dielectric substrate and inter-wound with the clockwise winding coil, wherein another end of the counter clockwise winding coils is on the first surface connecting to the third interconnection; wherein the third and second interconnections pass through the multi-layered dielectric substrate, wherein a part of the clockwise winding coil on the first surface has a projection on the second surface, and the projection is across a part of the counter clockwise winding coil on the second surface.
