The article discusses how using a Manufacturing Execution System (MES) can help semiconductor factories improve their manufacturing processes. By connecting different systems and collecting real-time information, MES can reduce costs, improve product quality, and make decision-making easier. The researchers designed a four-layer MES architecture tailored to semiconductor assembly and test manufacturing. Implementing this system at Intel factories led to significant improvements in competition advantage and production management. MES has proven to be a successful approach for enhancing high-volume manufacturing systems in the semiconductor industry.
