Claim 8:
9. A method of forming an electronic device, comprising:
forming first and second doped regions having a first conductivity type in a semiconductor substrate having a second conductivity type;
forming a dielectric layer between the first and second doped regions and a surface plane of the semiconductor substrate;
forming first, second, third and fourth terminals connected to the first doped region, the first and third terminals defining a first conductive path through the first doped region and second and fourth terminals defining a second conductive path through the first doped region, the second conductive path intersecting the first conductive path;
forming a first coil formed in an interconnect level over the first doped region, and a second coil formed in the interconnect level over the second doped region;
forming a well region having the second conductivity type located laterally between the first doped region and the semiconductor substrate and bounding a perimeter of the first doped region; and
forming a control circuit configured to produce a current that causes a first magnetic moment by the first coil and a second magnetic moment by the second coil, the first magnetic moment having a normal component with a first direction with respect to the surface plane, and the second magnetic moment having a normal component with a second opposite direction with respect to the surface plane.
