2D Traceability System
1. Purpose and Scope :
● Enhance product data traceability.
● Improve process control and recipe management.
● Meet and Exceed customer requirement.
2. System Diagram:
● Use 1×4 2D code to implement each chip traceability function.
● Choose green laser marking technology to print 2D code.
● Implement system and machine information communication at key stage by SECS/GEM standard
●Achieve product traceability level from Lot to chip
