  • Publication number: 20080303674
    Abstract: Communication between a scanner and a wireless IC tag is performed with certainty. An installation hole is formed in the side surface of a tire and a holder with wireless IC tag 10 housing a wireless IC tag 18 is inserted into this installation hole. The holder with wireless IC tag 10 can open and close. It is opened, the wireless IC tag 18 is housed in a pocket 20, the holder with wireless IC tag 10 is closed and inserted into the installation hole. The holder with wireless IC tag 10 housing the wireless IC tag 18 is inserted into the outer surface of the tire so a scanner can be brought close to the wireless IC tag 18, which can reliably communicate with the scanner. Further, the holder with wireless IC tag 10 is installed to the tire after vulcanization so there does not cause damage to the wireless IC tag 18 due to heat and the like.

In the semiconductor device which has the structure which stores a plurality of semiconductor chips with which plane sizes differ in the same sealing body in the state where they are accumulated via DAF, thickness of DAF of the back surface of the uppermost semiconductor chip with which the control circuit was formed was made thicker than each of DAF of the back surface of the lower layer semiconductor chip with which the memory circuit was formed. Hereby, the defect that the bonding wire which connects the uppermost semiconductor chip and a wiring substrate contacts the main surface corner part of a lower layer semiconductor chip can be reduced.
