Abstract

A method and system for fabricating solid-state energy-storage and energy-conversion devices including fabrication of films for devices without an anneal step, especially for the fabrication of supercapacitors and photovoltaic cells. A film is fabricated by depositing a first material layer to a location. Energy is supplied directly to the material forming the film. The energy can be in the form of energized ions of a second material. Supplying energy directly to the material and / or the film being deposited assists the growth of the crystalline structure of the film and controls stoichiometry.

Examples

embodiment 2500

[0279]FIG. 25A shows a perspective view of an embodiment 2500 of the present invention having an integrated circuit 2510 overlaid with a battery 2320. In some embodiments, integrated circuit 2510 includes a top insulator layer 2511 having a plurality of vias or openings 2512 to the active surface of the integrated circuit 2510 (the side with devices and connectors). Two of these vias are used as contacts 2514 and 2515 between integrated circuit 2510 and battery 2320. Battery 2320 is deposited as described for FIG. 23. In some embodiments, battery 2320 is deposited on an integrated circuit wafer before integrated circuit 2510 is diced apart from the other integrated circuits. In some embodiments, battery 2320 is deposited onto integrated circuit 2510 after integrated circuit 2510 is diced apart from the other integrated circuits. Some embodiments further include a passivation layer over the top and sides of battery 2320 such as layer 2331 of FIG. 23.

second embodiment

[0288] In one embodiment, further electronics are attached to the package / energy entity 2501 by way of adhesive. The electronics are then hardwired to the package / energy entity. In a second embodiment, the electronics are mounted directly to the package / energy entity by 2501 way of solder bumps. In some embodiments, the entire assembly is optionally potted, then sealed by the package cover. In other embodiments, the battery is formed on a substrate suitable as a packaging material. The substrate is formed into individual package form factors. The package with energy structure integrated is sent for assembly.

[0289] Thus, the present invention provides integrated product packaging and solid-state rechargeable batteries by cofabrication where the battery is deposited on the already-formed package. The present invention also provides integrated product packaging and solid-state rechargeable batteries by cofabrication where the battery is deposited on a suitable package material, then fo...
