Abstract
A method for integrating a thin film microbattery with electronic circuitry includes forming a release layer over a handler, forming a thin film microbattery over the release layer of the handler, removing the thin film microbattery from the handler, depositing the thin film microbattery on an interposer, forming electronic circuitry on the interposer, and sealing the thin film microbattery and the electronic circuitry to create individual microbattery modules.

A method for integrating a thin film microbattery with electronic circuitry, the method comprising:
- forming a release layer over a handler;
- forming a thin film microbattery over the release layer of the handler;
- removing the thin film microbattery from the handler;
- depositing the thin film microbattery on an interposer;
- disposing electronic circuitry on the interposer;
- and
- sealing the thin film microbattery and the electronic circuitry to create individual microbattery modules,
- wherein the thin film microbattery is disposed directly between the electronic circuitry and wherein all of the electronic circuitry directly contacts and extends above a topmost surface of the interposer.
