Abstract:
A method for creating a helix coil inductor having a body, said body being created over a surface of a silicon substrate having a plane, said surface of said silicon substrate having X and Y coordinates with corresponding X and Y axis perpendicularly intercepting, said point of intercept of said X and Y axis being an arbitrary point on a surface of said substrate, said helix coil having an axis having a direction, said direction of said axis being parallel with said surface of said substrate, comprising:creating a multiplicity of Nâˆ’1 lower level inductors, said Nâˆ’1 lower level conductors being located in a plane parallel with a plane of a surface of said silicon substrate; and creating a multiplicity of 2N vertical interconnects having a circular cross section, said 2N vertical interconnects having a radius located in a plane perpendicular with said plane of said surface of said silicon substrate, simultaneously creating a multiplicity of N upper level inductors located in a plane parallel with said plane of said surface of said silicon substrate, upper level connectors being separated from lower level conductors by a distance.
