MICROELECTRONIC SMART TAGS

摘要

A smart tag comprises a processor, a non-volatile memory, at least one of an internal power source and an external power source, and a transceiver configured for two-way communication with a reader external to the smart tag. The smart tag is formed as an integrated circuit chip less than 10 cubic millimeters in size to less than 0.000125 cubic millimeters in size. An apparatus comprising the smart tag may further include an antenna connect to the smart tag.

主权项

1. A smart tag comprising:
a processor; a non-volatile memory; an internal power source; and a transceiver configured for two-way communication with a reader external to the smart tag; wherein the smart tag is formed as an integrated circuit chip less than 10 cubic millimeters in size; wherein the integrated circuit chip comprises:
a silicon die comprising at least the processor;a dielet formed over the silicon die and comprising at least a portion of the internal power source via one or more capacitors formed therein; anda photovoltaic reflector formed over the dielet, the photovoltaic reflector comprising a photovoltaic layer comprising at least a portion of the internal power source and a reflector providing at least a portion of the transceiver; and wherein the silicon die, the dielet and the photovoltaic reflector are interconnected using at least one micro controlled-collapse chip-connection interconnect.
