Abstract:
An inductive system formed over a semiconductor substrate, the system comprising:a first inductor having a longitudinal centerline and a first conductor that spirals around the longitudinal centerline a plurality of times to form a plurality of loops, each loop having: a first vertical segment having a plurality of first vias, the first vertical segment being vertical with respect to a surface of the substrate, each first via being vertically spaced apart, no first via being formed directly vertically over another first via, a second vertical segment having a plurality of second vias, the second vertical segment being vertical with respect to the surface of the substrate, each second via being vertically spaced apart, no second via being formed directly vertically over another second via, a first horizontal segment that is connected to the first vertical segment and the second vertical segment, the first horizontal segment being horizontal with respect to the surface of the substrate, and a second horizontal segment that is connected to the second vertical segment, the second horizontal segment being horizontal with respect to the surface of the substrate.
