Lighthouses are designated by an independent panel of experts based on their effective use of AI, industrial Internet of Things (IIoT), big data analytics, and other digital technologies. The Global Lighthouse Network, co-founded in 2018 by the World Economic Forum and McKinsey & Company, now spans over 30 countries and 35 sectors.
UMC formed a dedicated smart manufacturing division in 2017, and appointed Fab 12A as the pilot fab for digital transformation initiatives, which are subsequently deployed to other UMC sites. To date, more than 48 4IR solutions have been successfully integrated into Fab 12A’s operations and value chain, nearly
TS Wu, Vice President of UMC and Head of Digital Office, said, “We are honored to be recognized by the World Economic Forum as a frontrunner in adopting smart manufacturing solutions at scale to transform our business. 4IR is at the center of UMC’s sustainable development, ensuring we can meet customers’ demands in an increasingly competitive market. Smart manufacturing is also about empowering our employees to focus on higher-value work and optimizing resource use to reduce environmental impact. We are excited to serve as a beacon for other manufacturers seeking to harness digital tools as well as to learn from other Lighthouses in the network.”
UMC focuses on the production of specialty semiconductors, which have higher value but poses complex manufacturing challenges with their unique functionalities and strict performance specifications. The 4IR use cases deployed have helped overcome these challenges and expanded customer engagements for UMC’s specialty portfolio, enhancing the company’s overall profitability.
To accelerate time to market for customers, UMC leveraged machine learning tools to shorten design kit creation lead time for new fabrication processes by more than half. To ensure accuracy and timely delivery of photomasks, UMC developed an AI-enabled platform to streamline data handling between the company, customer, and photomask vendor.
In order to reduce cycle time, UMC deployed a machine learning predictive model and intelligent gas deployment system to target key bottleneck tools. Additionally, an intelligent defect root cause analysis system was created, incorporating smart image recognition and automatic AI deciders, to quickly identify process weaknesses and suspected tool issues. This system greatly increased efficiency in defect root cause identification and tool troubleshooting, effectively improving yields.
The Fab 12A site spans three separate but connected fabs, with inter-fab production enabled by an intelligent Automated Material Handling System (AMHS). With 3,000 pieces of equipment and 68 million possible routes a wafer can take throughout its manufacturing process, UMC integrated AI algorithms with the standard AMHS to automatically assign the optimal route. This enhanced worker efficiency and also improved the utilization rate of tools and transportation vehicles.
