Patent ID: 7230316

Claim:
A semiconductor device comprising: a circuit board; at least first and second terminals formed on the circuit board; a first adhesive agent formed on the circuit board; a first functional circuit peeled from a first processing substrate at a first tungsten oxide layer, and mounted over the circuit board with the first adhesive agent therebetween, the first functional circuit comprising: a first electrode electrically connected to the first terminal; a first insulating film on the first electrode and the first adhesive agent; a thin film transistor over the first insulating layer wherein the first electrode is electrically connected to the thin film transistor; and a second insulating film over the thin film transistor; a residual of the first tungsten oxide layer over the second insulating film; a heat sink formed over the residual of the first tungsten oxide layer, and over the first functional circuit; a second adhesive agent formed on the circuit board; a second functional circuit peeled from a second processing substrate at a second tungsten oxide layer, and mounted over the circuit board with the second adhesive agent therebetween, the second functional circuit comprising: a passive element; a third insulating film over the passive element; a residual of the second tungsten oxide layer over the third insulating film; and a second electrode on the residual of the second tungsten oxide layer wherein the second electrode is electrically connected to the second terminal; an antenna pattern formed over the second functional circuit, electrically connected to the second functional circuit through the circuit board.
