Abstract
An electronic device includes a base substrate with a mica substrate thereon. A top face of the mica substrate has a surface area smaller than a surface area of a top face of the base substrate. An active battery layer is on the mica substrate and has a top face with a surface area smaller than a surface area of a top face of the mica substrate. An adhesive layer is over the active battery layer, mica substrate, and base substrate. An aluminum film layer is over the adhesive layer, and an insulating polyethylene terephthalate (PET) layer is over the aluminum film layer. A battery pad is on the mica substrate adjacent the active battery layer, and a conductive via extends to the battery pad. A conductive pad is connected to the conductive via. The adhesive, aluminum film, and PET have a hole defined therein exposing the conductive pad.
