Due to the prevailing use of automotive chips in recent years, their relevant safety regulations have become more stringent. An MES system can play a crucial role in managing and controlling the production process; especially in the semiconductor industry, which holds even higher standards for manufacturing and related systems.

Chroma Sajet MES (manufacturing execution system) has been deeply involved in the semiconductor industry for many years. The standard version's functionality has matured to a highly comprehensive product with flexible expansion for specific requirements. With over 15 years of experience in the field, Chroma's semiconductor consultant not only clearly understands customers' needs but also can guide customers to pinpoint and solve problems.

Wafer Works Corporation is one of the world's top ten silicon wafer manufacturers in the semiconductor industry. The company's Zhengzhou plant has complete and independent R&D capabilities for growing, slicing, and polishing silicon wafers. The factory implemented Chroma Sajet MES to collect and process production records and yield information, control and track the number of processing products, manage the process flow, analyze indirect data, and monitor the production quality status of each work station as well as SPC in real-time. The result is more transparent data from the production line.

Reasons for Wafer Works(Zhengzhou) Corporation to adopt Chroma Sajet MES include:

• The functions of the Chroma Sajet MES standard version are very thorough, reducing the investment costs while improving the system stability.
• Sajet MES complies with 8-inch and 12-inch wafer manufacturing systems and IT standards, completely integrating into automated fab.
• It can flexibly integrate heterogeneous systems, making the business process even more complete and automated.
• Chroma has rich experience in integrating MES to semiconductor manufacturing to speed up the implementation process.
• The combination of the Chroma Group's R&D resources with various automation products allows the integration of the plant with a complete automated test system, improving the factory's production efficiency, reducing the time and cost of installation and maintenance, and quickly solving any problems throughout the factory.
