In the semiconductor industry, known for its nanometer-level precision, even a speck of dust invisible to the naked eye can cause a wafer worth tens of thousands of yuan to be scrapped.
But even more insidious than physical contamination is "data contamination" in the production process—misaligned IDs from manual transcription, gaps in process parameter traceability, and isolated equipment information... These invisible killers are eroding the yield and efficiency of chip manufacturing.
Semiconductor manufacturing is undergoing a paradigm shift from "experience-driven" to "data-driven"!
Two hidden pain points in semiconductor factories:
1. Manual operation of the minefield: After loading the material, manually triggering the ID reading is like suddenly braking on a highway - data delay and error directly affect the stability of the process. A 12-inch wafer fab once had to rework an entire batch of products due to ID misreading, resulting in a direct loss of over one million.
2. Tracing the black hole swallowing yield: When an anomaly occurs on a wafer, engineers need to search through paper records like detectives, often spending hours to locate the problematic process, and process optimization is impossible.
A game-changer has arrived! RFID + SECS standards are reshaping the DNA of intelligent manufacturing.
Superisys Semiconductor RFID Traceability System, a world-leading intelligent semiconductor system
A "data revolution" is unfolding in 300mm wafer fabs:
By building a fully automated data link through the SECS/SEMI standard protocol and combining it with high-performance RFID technology, real-time tracking, data transparency, and intelligent decision-making can be achieved throughout the entire wafer manufacturing process.
Semiconductor RFID Application Solution Architecture Diagram
Automatic reporting process:
1. Connect RFID, IO module, sensor and LED tri-color light;
2. Place the wafer cassette containing the capsule on the loadport machine;
3. Once the machine's pressure sensor detects the pressure, the input terminal of the I/O module is triggered;
4. After the RFID control box senses the input from the I/O module, it actively reads the ID of the wafer capsule and reports it to the EAP system after successful reading.

Low-frequency RFID controller RF-LC12097
Low-frequency RFID reader RF-LA5010
1. Application Instructions
An RFID chip RF-LT-DR2B is installed on the LoadPort containing the wafers. An RFID controller RFLC12097 and an RFID reader/writer RF-LA5010 are installed at the loading and unloading positions of each process segment. The RFID reader/writer accurately identifies the RFID chip on the LoadPort, obtains all wafer information (processing technology, processing data) on the LoadPort, uploads it to the ERP system, and realizes the docking with the field equipment, production information data collection and transparent transmission, anomaly handling, etc., thus improving the construction of data informatization.

2. Application Purpose
After replacing manual feeding, the button triggers the host computer to read the ID, and the material box actively reports the ID when it is in place, allowing for the tracing of the completed process flow.
3. Application Effect
Helping the semiconductor industry achieve refined management
Improve yield: Reduce human error and ensure 100% traceability of process data;
Cost reduction and efficiency improvement: Fully automated data collection reduces labor costs and accelerates production cycle time;
Intelligent decision-making: Real-time data dashboards facilitate process optimization and predictive maintenance.
4. Core Advantages
01 Accurate identification and proactive reporting
By integrating an industrial-grade RFID carrier (RF-LT-DR2B) into LoadPort, and working with high-sensitivity read/write heads (RF-LC12097) in each process stage, the ID is automatically reported when the wafer box is in place, completely replacing manual triggering.
Millisecond-level response ensures data real-time performance and accuracy.
02 End-to-end traceability, data closed loop
Real-time acquisition of wafer fabrication technology and process data, and seamless integration with MES/ERP systems to build a complete production information database;
It supports forward tracing (current process status) and reverse tracing (historical process path) to help quickly locate the root cause of anomalies.
03 SECS/SEMI Standardization Integration
Based on the SECS/GEM protocol, efficient communication between devices is achieved, breaking down information silos and improving system compatibility and scalability;
Compliant with SEMI international standards, ensuring the solution's universality and reliability in the semiconductor industry.

What's happening in wafer fabs in the Industry 4.0 era? As RFID tags become the "digital DNA" of each wafer, and as the SECS protocol weaves the neural network of smart factories, semiconductor manufacturing is shifting from "experience-driven" to "data-driven." In the future, predictive maintenance and adaptive process adjustments combined with AI will become possible—this is the true potential of smart manufacturing.
With the development of Industry 4.0 and the upgrading of intelligent manufacturing in the semiconductor industry, RFID technology will become the core infrastructure for the digitalization and intelligentization of wafer fabs. We will continue to focus on high-reliability RFID+SECS/GEM integrated solutions to provide global semiconductor customers with superior transparent factory solutions!
