Abstract
RF ID transmitter circuits are integrated into semiconductor chips during fabrication of the regular integrated circuits therein for providing identification capabilities for the semiconductor chips that comply with the IEEE family of standards 802. The RF ID transmitter circuit enables each chip to be identified in many different environments and at any of the stages after its fabrication, including inspection, distribution and commercial usage of the chip.
Claims16
A semiconductor chip comprising:
- an integrated circuit (IC) fabricated on a substrate;
- and
- RF ID (identification) circuitry fabricated on said substrate during fabrication of the IC, wherein a portion of said RF ID circuitry emits an RF signal to identify said semiconductor chip, said RF ID circuitry complying with an IEEE family of standards 802 for local area networks (LANs) and metropolitan area networks (MANs).
A method of fabricating a semiconductor chip comprising:
- fabricating an integrated circuit (IC) on a substrate;
- and
- simultaneously fabricating RF ID (identification) circuitry on said substrate during fabrication of the IC, wherein a portion of said RF ID circuitry emits an RF signal to identify said semiconductor chip, said RF ID circuitry complying with an IEEE family of standards 802 for local area networks (LANs) and metropolitan area networks (MANs) and including a unique Organizationally Unique Identifier (OUI) to an organization which is three octets (24 bits) in length, wherein the second least significant bit (LSB) is always a zero (0).
