First Claim
Patent Images
1. A method of fabricating a vertically integrated and electrically interconnecting a thin-film type battery on an electrical or electronic device, comprising:
- on an electrical or electronic device having a pair of terminals, forming an electrically non-conductive insulating layer for covering at least a part of an outer surface of the device;
forming vertical contact holes in the insulating layer for exposing the pair of terminals of the device therethrough;
filling the contact holes with an electrically conductive material for forming a pair of vertical conductors in respective contact with corresponding ones of the pair of terminals of the device;
forming a pair of electrically conductive electrode conductors laterally spaced from one another on an outer surface of the insulating layer and in respective contact with corresponding ones of the vertical conductors;
forming a cathodic thin film on one of the pair of electrode conductors;
forming an electrolytic thin film on the cathodic thin film; and
forming an anodic thin film on the electrolytic thin film, on an intervening portion of the outer surface of the insulating layer and on the other one of the pair of electrode conductors.

Abstract
An electrical or electronic device and a thin-film type battery are vertically integrated and interconnected for reducing the area occupied thereby, enabling a higher degree of device integration and simplifying their fabrication. An insulating layer is formed on the device, with vertical conductors extending respectively from a pair of terminals of the device through the insulating layer. Electrode conductors are formed on the insulating layer in contact with the respective vertical conductors and serve as the cathode and anode electrodes of a thin-film battery fabricated thereon.
