Patent ID: 8550345

Claim:
An RFID (radio frequency identification) real-time information system accommodated to a semiconductor supply chain for exchanging real-time information corresponding to a plurality of wafers across the semiconductor supply chain, wherein the semiconductor supply chain essentially comprises at least one wafer vendor, at least one wafer testing vendor and at least one packaging vendor, each said wafer vendor, said wafer testing vendor, and said packaging vendor having a predetermined space provided with a plurality of carriers, in which each the plurality of carriers is used to hold at least one wafer, the RFID real-time information system accommodated to the semiconductor supply chain being characterized by comprising: a plurality of RFID tags, attached respectively to the plurality of carriers in the predetermined space in each said wafer vendor, said wafer testing vendor and said packaging vendor has the predetermined space, wherein each the plurality of RFID tags has a tag information; a plurality of RFID readers, distributed in the predetermined space of each said wafer vendor, said wafer testing vendor and said packaging vendor for reading or writing the tag information of each said plurality of carriers from or into said plurality of RFID tags via radio frequency; an RFID middleware module, for generating a stock and logistic information from the tag information corresponding to the plurality of carriers and the plurality of wafers; a manufacturing information module, for storing an object information corresponding to the plurality of wafers; a real-time information module, for integrating the RFID middleware module with the manufacturing information module to generate real-time information corresponding to the plurality of carries and the plurality of wafers; and a business-to-business (B2B) e-commerce module, comprising a plurality of B2B servers disposed respectively in said wafer vendor, said wafer testing vendor and said packaging vendor of the semiconductor supply chain for connecting and exchanging the real-time information through a standard protocol of e-commerce; wherein said real-time information comprises a first real-time information at an end of said wafer vendor, a second real-time information at an end of said wafer testing vendor and a third real-time information at an end of said packaging vendor in which the first real-time information represents logistic information corresponding to the wafers, the second real-time information represents logistic information, testing information and stock information corresponding to the wafer and the third real-time information represents logistic information corresponding to the wafers.
