RFID technology is a non-contact automatic identification technology, through the radio frequency signal to automatically identify the target object and obtain relevant data. It is mainly composed of RFID tags, readers and antennas. The tag stores the information of the recognized object, when the object with the tag enters the RF field of the reader, the tag is activated, and the data is transmitted through the antenna and the reader, which reads the tag information and transmits it to the system for processing. The technology does not require physical contact, can quickly and accurately identify the target in complex environments, has the advantages of waterproof, dustproof, anti-magnetic, long service life, etc. It is very suitable for the production environment of the semiconductor industry.

3. Application Scenarios and Equipment Selection
3.1 Semiconductor production line
Deploy the TI glass tube tag on the wafer box, and then identify the material model, specification, processing flow and other information inside the glass tube tag of the wafer box through semiconductor RFID read-write, so as to accurately control and adjust the production process. You can choose semiconductor RFID reader:
3.2 Wafer storage cabinet management
Industrial RFID read-write embedded in the storage cabinet bearing platform support board, when the wafer box into the storage cabinet, semiconductor RFID read-write recognition TI glass tube tags, access to the goods information of the wafer box, to confirm whether the wafer box is stored correctly, while access to the wafer chip storage location, when necessary, can be immediately found in the stored wafers.
3.3 Wafer silicon wafer cleaning
Semiconductor RFID read-write will be deployed in the wafer wafer cleaning station above, when the wafer box equipped with TI glass tube tags are sent to the cleaning area, semiconductor RFID read-write will automatically read and determine whether the wafer box arrives at its preset position. After the cleaning operation is completed, the collected TI tag information will be uploaded to the management system, and at the same time, the wafer wafers that have completed the cleaning step will be labeled. When the semiconductor RFID reader reads the tag again, it can be informed of which processes have been completed on the wafer, thus preventing process confusion.
4. semiconductor overhead crane management
Site identification: RFID tags installed on the track of the semiconductor crane, semiconductor RFID read-write deployed in the crane, when the RFID read-write receives the RFID tags at the site of the vehicle track, you can get the crane’s location information, real-time dynamic monitoring of the location of the crane, and according to its own location of the line planning and scheduling, to ensure that the crane’s operating safety distance and transportation efficiency.
Handling Management: When the FOUP wafer box is being handled by the truck, the semiconductor RFID reader receives the relevant information from the TI glass tube tag to ensure that the FOUP wafer box being handled is accurate. In driving to the corresponding storage / placement location, semiconductor RFID read-write again to identify the destination of the tag information, and will be consistent with the information of the FOUP wafer box to the appropriate location, at the same time will be taken to the placement of all the information uploaded to the management system at the time.
5. E-Rack electronic shelf
Mainly consists of: LED display, card reader, centralized control and management software; E-Rack type: 4 * 5 type, 3 * 4 type, 3 * 5 type, as well as AGV-electronic material rack;
The semiconductor RFID reader is installed at the back of the identification position of the semiconductor electronic shelf. When a wafer cartridge is placed on the Semiconductor E-Shelf, the Semiconductor RFID reader located on the identification position will read the TI tag through infrared sensing and trigger the antenna to collect the information of the wafer cartridge. At the same time, the display on the front of the semiconductor electronic shelf will show the type of wafer product in real time. When the cassette is removed, the semiconductor RFID reader is unable to sense the presence of the TI tag and will indicate on the display that the corresponding product has been removed.
