Patent ID: 8609464

Claim:
A method for manufacturing a semiconductor device comprising: sealing a plurality of element layers each containing a semiconductor integrated circuit and an antenna between a first insulator and a second insulator; forming a layered structure containing a first conductive layer, the first insulator, the plurality of element layers, the second insulator, and a second conductive layer, wherein the first insulator, the plurality of element layers, and the second insulator are interposed between the first conductive layer and the second conductive layer; and melting the first insulator and the second insulator after forming the first conductive layer and the second conductive layer, whereby the layered structure is divided so as to include at least one of the semiconductor integrated circuits and one of the antennas, wherein the first conductive layer and the second conductive layer are electrically connected to each other simultaneously with the step of melting the first insulator and the second insulator.
