The invention discloses a radio frequency identification (RFID) real-time common information system for transferring the real-time information of a plurality of wafers among manufacturers in a semiconductor supply chain system. Each manufacturer has a default space for being provided with a plurality of carriers, and each carrier is used for carrying at least one wafer. The RFID real-time common information system comprises a RFID mediation module, a production process data module, a real-time information module and an enterprise electronic commerce module, wherein the RFID mediation module generates the location and logistics information of the carriers and the wafers by label information; the production process data module stores object information which is relevant to the wafers; the real-time information module integrates the RFID mediation module and the production process data module so as to generate the real-time information of the carriers and the wafers; and the enterprise electronic commerce module comprises a plurality of B2B servers which are respectively arranged in the semiconductor supply chain system, connected by an electronic commerce standard protocol and exchange the real-time information.
Description
technical field [0001] The invention relates to a real-time common information system of a semiconductor supply chain system, in particular to a real-time common information system of a semiconductor supply chain system integrating radio frequency identification (RFID) technology. Background technique [0002] The prior art about using RFID technology to store or ship wafers is disclosed in US Patent US6330971, US Early Published Application US20060043197 and Taiwan Patent TW I267029. Among them, the U.S. invention patent US6330971 discloses a system that uses RFID technology to track chips, such as Figure 1A As shown, the system 10 includes a plurality of carriers 11 carrying wafers, an RFID reader 12, an RFID tag 14 attached to the carrier 11, and a controller 13, wherein the RFID reader 12 utilizes a plurality of antennas thereon 15 to read the RFID tags 14 attached to each carrier 11, and at the same time, the RFID reader 12 transmits the read tag information to the con...
