The adhesive used in this application extends to any material capable of adhering the electrochemical element 315 to the barrier layer 307. The adhesive may produce either a mechanical or chemical bond between the two layers. The adhesive may also include chemically adhering the two layers without introducing another material or layer. The adhesive may include, but is not limited to, for example, a cement adhesive and a resin-based adhesive. The adhesive may be electrically a conductor, a semiconductor, or an insulator.
0051In another embodiment, the flexible printed circuit board 305 functions as a substrate for the battery and the barrier layer 307 may be deposited on it. Further, the barrier layer 307 may be adhered to the flexible printed circuit board 305. Upon preparing the barrier layer 307 and the printed circuit board 305, the electrochemical element 315 may be deposited directly on the barrier layer 307.
0052Although FIGS. 4A and 4B show only one conductor 120, 320, respectively, an exemplary embodiment is at least one second conductor, such as the conductors 121, 321 mentioned above in relation to FIGS. 1A and 3A, respectively. Please understand that it may include. Further, the electrical connection between the first contacts 101, 301 and the underlying semiconductor surface or conductive or insulating surface of the semiconductor device, or flexible circuit board is via an adhesive layer and / or a barrier layer. It may be made by conductors 121 and 321.
0053Also, the above exemplary embodiments may include a large number of electrochemical elements stacked on the semiconductor surface or conductive or insulating (eg, package) surface of the semiconductor device.
0054In addition, the above exemplary embodiment may include a large number of electrochemical elements stacked on the first electrical contact section 301.
0055This exemplary embodiment provides an alternative scheme for encapsulating chemically and mechanically sensitive layers of electrochemical devices and is cheaper than conventional encapsulation schemes using gold leaf. Also, the above exemplary embodiments relate to rupture of the seal of the metal and plastic bag encapsulating the electrochemical element resulting from temperature changes that expand and / or contract the gas in the metal and plastic bag. Avoid scheme problems as well.
0056The exemplary embodiments described herein also provide a rechargeable second battery that is machined directly onto a semiconductor device such as an integrated circuit. Such batteries supply power when the circuit is powered off and are quickly and easily recharged when power is resumed. Important electrical circuits can benefit from the local power supplied by such batteries. Illustrative embodiments also provide a cheaper and more reliable encapsulation approach, as well as a better approach for providing electrically conductive contact, including encapsulation that is significantly thinner than known encapsulation methods. .. An exemplary embodiment also provides a flexible integrated circuit and / or a flexible printed circuit board with a thin film flexible battery coupled therein.
0057The above embodiment describes the conductive material provided in the openings in the adhesive layer such as slits, but the electrical contact between the battery cell structures 115, 315 and the first electrical contacts 101, 301 is It should be understood that it may be provided by various other methods. For example, by embedding a conductive powder in the adhesive forming the adhesive layers 110, 310, electrical conduction may be provided between the cell structures 115, 315 and the first contacts 101, 301. For example, conductive powders such as metal powders (eg, nickel powders) are used in one or more selected portions of the adhesive adhesive layers 110, 310, and the adhesives 101, 301 and the battery cell structures 115, 315. Can be embedded in the adhesive adhesive layers 110, 310 between and. Those skilled in the art should understand other conductive materials that may be provided for selective conduction such as conductive balls, slags, wiring meshes, etc. that are selectively provided within the adhesive. A method of providing electrical conduction between the battery cell structures 115, 315 and the first contacts 101, 301 and further providing insulation between the contacts and the battery cell structure is an example described herein. Should not be considered as limiting.
0058The same applies to the electrical contact between the battery cell structures 115, 315 and the semiconductor surface or conductive or insulating package surface of the semiconductor element 105, or the flexible printed circuit board 305. The same applies to the electrical contact between the first contact portions 101, 301 and the semiconductor surface of the semiconductor element 105 or the surface of the conductive or insulating package, or the flexible printed circuit board 305.
0059Further, the electrochemical device may include an individual device (eg, fully packaged with its own substrate and its own encapsulation) on the semiconductor surface, conductive or insulating surface or flexible printed circuit board of the semiconductor device. Please understand that it is good. For example, prior to the integration of a semiconductor device onto a semiconductor surface or a conductive or insulating surface, or into or on a flexible printed circuit board, the electrochemical device is processed as a separate element and then the substrate. And may be integrated as a whole with its encapsulation.
0060The above embodiment is merely an example. One of ordinary skill in the art will recognize variations from the embodiments specifically described herein that are intended to be included within the scope of this disclosure. In a strict sense, the invention is limited only by the claims below.
