1. An inductor, comprising:
- a first dielectric layer formed over a semiconductor substrate, the first dieledric layer patterned to form a first row having alternating pedestals and trenches;
a second dielectric layer formed over the semiconductor substrate, the second dielectric layer patterned to form a second row having alternating pedestals and trenches that is adjacent to the first row;
a first magnetic layer formed over the first row and the second row, the first magnetic layer comprising an amorphous alloy which includes cobalt;
a third dielectric layer formed over the first magnetic layer and forming an interconnect portion connecting the first row to the second row;
a conductive layer formed conformally over the third dielectric layer to form a signal path along the first row, the interconnect portion, and the second row.
