Wan Zhengfeng, vice mayor of Zhengzhou, and his party went to Sai Microelectronics for investigation and research.

On May 26, 2020, Wan Zhengfeng, Deputy Mayor of Zhengzhou City, Henan Province, Li Bing, Deputy Secretary-General, Director of the Municipal Bureau of Commerce, and Wu Ande, Deputy Director of the Municipal Bureau of Commerce, visited Sai Microelectronics to have a comprehensive understanding of the company's business and other situations, and conduct in-depth exchanges on the development prospects of semiconductor business. Saiwei Electronics Chairman Yang Yunchun, Director and General Manager Zhang Yunpeng and other company leaders gave a warm reception and organized talks. At the

meeting, Chairman Yang Yunchun introduced the basic situation, main business and core advantages of Saiwei Electronics to the visiting leaders in detail, and focused on the latest progress of the company's semiconductor business development.

In semiconductors, Sai Microelectronics focuses on developing two strategic businesses, MEMS and GaN. Up to now, the construction of the "8-inch MEMS International OEM Line Construction Project" jointly invested and constructed by the company and the National Integrated Circuit Industry Fund is nearing completion. The factory equipment and the process equipment required for the first phase of production capacity have been purchased and moved into the factory. The equipment installation work is being rapidly promoted and is expected to be put into production in the third quarter of this year. After the company's GaN epitaxial wafer production line is put into operation, it will begin to verify supply to international famous manufacturers; in April this year, the company successfully developed 650 V series GaN power device products and released PD fast charging application examples based on this series of GaN power devices, providing high-performance and cost-effective domestic technology solutions for GaN fast charging fields with strong demand at present.

Vice Mayor Zhengfeng fully affirmed the rapid development of Saiwei Electronics. He believes that with the rapid popularization and application of the Internet of Things and 5G technology, the semiconductor industry is ushering in a new round of rapid development. Saiwei Electronics should seize the opportunities of the times, actively give full play to its own advantages, and strive to achieve a new leap in the enterprise in the opportunities and challenges.

As the capital city of Henan Province and a national central city under construction, Zhengzhou is an important railway, aviation, electric power, postal and telecommunications hub city in the country. It is also the "Zhengzhou Power" for the rise and high-quality development of the central region. High-end manufacturing and other supporting capabilities, with deep industrial accumulation in the sensing field, are currently planning to build the "China (Zhengzhou) Intelligent Sensing Valley". Deputy Mayor Wan Zhengfeng said that high-tech companies such as Saiwei Electronics are welcome to visit Zhengzhou and expand their business. The Zhengzhou Municipal Government will also give the greatest support from various policies to achieve a win-win situation for both parties through in-depth cooperation.

Chairman Yang Yunchun expressed his gratitude to Vice Mayor Wan Zhengfeng and his party on behalf of Saiwei Electronics. He said that Saiwei Electronics will keep up with the pace of the times, deeply cultivate industry technology and applications, continue to give full play to the company's advantages in high-end manufacturing and other aspects, and strive to promote the high-quality development of the industry. At the same time, he is also very willing to go to Zhengzhou to study and explore industrial cooperation in the sensing field.

The two sides will further communicate and discuss specific exchanges and cooperation matters.
