<p>In one embodiment, a wireless tag includes a wireless transceiver, a memory and an antenna all formed on a thin film substrate where the substrate includes one or more openings formed thereon. The opening in the substrate enables the flow of encapsulation material when the wireless tag is embedded into a semiconductor package. In another embodiment, a wireless tag is attached to the package substrate of a semiconductor package where the thin film substrate of the wireless tag has an opening sufficient to accommodate the integrated circuit die of the semiconductor package. In another embodiment, a wireless tag is formed using a metal film as the antenna and a wireless element attached to the metal film. The wireless tag is attached to the package substrate of a semiconductor package using a non-conductive adhesive. The metal film includes an opening sufficient to accommodate the die of the semiconductor package.</p> |
