ABSTRACT:
A chip-battery micro-module and fabrication method thereof wherein an integrated circuit "chip" is secured to a battery coin cell using various conductive and insulative layers that provide power to the chip while also forming a protective structure for protecting the chip. The chip-battery micro-module may be used to power an electronic accessory which is directly attached thereto, such as an LCD display or speaker, or to power a circuit in a smart card or electronic device such as a portable telephone. The chip may be secured to the battery using epoxy layers, epoxy bodies, dielectric layers, and plasma- or vapor-deposited layers. The above elements may be conductive or insulative as required. The chip-battery micro-module can be integrated into a plastic smart card. The use of the rigid battery coin cell provides the chip-battery micro-module with improved strength characteristics for withstanding loads and impacts during assembly and handling. Moreover, this protection can be extended to other components that are packaged with the chip as an assembly, such as electronic accessories. Furthermore, electromagnetic shielding and heat sink properties may be realized.
