Abstract
A method of forming a semiconductor device includes: forming a passivation layer over a conductive pad that is disposed over a substrate; and forming an inductive component over the passivation layer, including: forming a first insulation layer and a first magnetic layer successively over the passivation layer; forming a first polymer layer over the first magnetic layer; forming a first conductive feature over the first polymer layer; forming a second polymer layer over the first polymer layer and the first conductive feature; patterning the second polymer layer, where after the patterning, a first sidewall of the second polymer layer includes multiple segments, where an extension of a first segment of the multiple segments intersects the second polymer layer; and after patterning the second polymer layer, forming a second insulation layer and a second magnetic layer successively over the second polymer layer.
