  • Publication number: 20220285079
    Abstract: An inductor can be formed in a coreless electronic substrate from magnetic materials and/or fabrication processes that do not result in the magnetic materials leaching into plating and/or etching solutions/chemistries, and results in a unique inductor structure. This may be achieved by forming the inductors from magnetic ferrites. The formation of the electronic substrates may also include process sequences that prevent exposure of the magnetic ferrites to the plating and/or etching solutions/chemistries.
