This invention pertains to the embedding of a information storage device within, or attached to, the carriers used to transport work in progress from step to step in the semiconductor manufacturing process. The carrier can be a tray having sites for several semiconductor dies, tubes for carrying several dies together, lead frames, wafer cassettes or individual die sockets. The information storage device can be formed integrally with the carrier or formed separately and attached or secured to the carrier.
