  • Publication number: 20040181938
    Abstract: Clean accommodation and carrying of semiconductor devices are to be attained. A stack type tray is used which comprises a base portion 1d with plural pockets formed therein in a matrix shape and side walls formed along peripheral edges of the base portion. In the tray is buried an electronic tag which is constituted by a mu-chip having memory with non-contact recognizable information stored therein. Information pieces such as ID, manufacturer's name and product number of the tray, as well as product name, quantity and lot number of an object to be accommodated, are stored in the mu-chip of the electronic tag, and by accommodating a to-be-accommodated object in the tray equipped with the mu-chip and carrying it, the generation of dust can be prevented because paper label is not used.
