The person in charge of the shareholder unit of Saiwei Electronics visited Fab Base for investigation.

Recently, Mr. Lu Jun, President of Huaxin Investment, the investment management agency of the National Integrated Circuit Industry Investment Fund Co., Ltd., Mr. Ren Kai, Vice President, Mr. Liu Yang, General Manager of Investment Department II, and Mr. Zhao Ye, Deputy General Manager of Investment Department II, ms. Liu Xinyu, Managing Partner of Shengshi Investment Management, Beijing Integrated Circuit Manufacturing and Equipment Equity Investment Center (Limited Partnership), and Mr. Yin Yue, Managing Director, visited the 8-inch MEMS base under construction in Beijing, a subsidiary of Saiwei Electronics. Mr. Yang Yunchun, chairman of Saiwei Electronics, and relevant responsible personnel of the group and subsidiaries were warmly received. Mr. Yang Yunchun, Chairman of

Company, sincerely welcomed the heads of large funds and Beijing fund investment management agencies to the company's MEMS base in Beijing Economic and Technological Development Zone, and reported on the construction of the Beijing MEMS production line of Saiwei Microelectronics and the development of related businesses. In the context of the COVID-19 epidemic, international and domestic logistics and personnel exchanges have been affected to varying degrees, part of the construction of the base project and part of the mechanical and electrical equipment installation and commissioning, trial production arrangements have been affected to varying degrees. The company has made great efforts to overcome various difficulties caused by the epidemic. Up to now, the construction of the base factory building is nearing completion, and the main factory building and support floor area are nearing completion. All functional systems of the power plant have been installed in place. The bulk gas station and chemical warehouse have been completed. Office floors and shift apartments are being renovated. Clean rooms required for phase I capacity are ready, and equipment required for phase I capacity has entered the factory, the plant service system has started to operate and debug, and the production equipment has been moved in and installed and debugged. At present, the secondary piping and wiring of the production equipment is under construction, and the operation and debugging of the plant service system and production equipment of the whole production line will be started one after another.

The heads of major funds and Beijing fund investment management agencies have fully understood the company's concerns. After listening to the report and discussion, Mr. Lu Jun, President of Huaxin Investment, fully affirmed the operation of the Swedish production line in Saiwei MEMS business. At the same time, he further emphasized the importance of the completion and operation of Beijing MEMS production line, encouraged the company to continue its efforts to realize the trial production of this large-scale production line as soon as possible, and put forward constructive opinions and suggestions on the future development mode and ideas of Saiwei MEMS business.

Sweden Silex, a wholly-owned subsidiary of Sai Microelectronics, was established in 2000. It has long focused on MEMS chip process development and wafer manufacturing. It has the world's advanced pure MEMS foundry technology and expanding foundry capacity. Sweden Silex is a leading foundry manufacturer of MEMS chips (communications, biomedicine, industrial science, consumption, etc.) in the world. Since 2012, sweden Silex has always been in the first echelon of MEMS wafer foundry in the world. In the 2018 ranking of global MEMS wafer manufacturers, Sweden Silex continues to rank second among pure manufacturers and fourth among manufacturers, ranking in the top five in the world together with STMicroelectronics, TELEDYNE DALSA, SONY and TSMC.

Sweden Silex has mastered many process technologies and process modules with international leading competitiveness in the industry, such as through silicon via hole, wafer bonding, deep reactive ion etching, etc. It has the most advanced through silicon via hole insulation layer process platform (TSI) in the industry at present. It has a production history of more than 10 years and has produced more than hundreds of thousands of wafers and more than 100 different products, the technology can be extended and transplanted to 2.5D and 3D wafer-level advanced packaging platforms. It has provided process development services for more than 400 MEMS chips for global manufacturers, and has produced a variety of MEMS products including micromirrors, microneedles, silicon photons, on-chip laboratories, microbolometers, oscillators, atomic clocks, ultrasound, pressure sensors, accelerometers, gyroscopes, silicon microphones, etc. for customers; silex currently has two mature, industry-leading 8-inch MEMS production lines in Sweden.

Sai Microelectronics has been committed to promoting the integration of its MEMS business resources, with Sai Lex International coordinating the company's MEMS business resources. After the completion of the Beijing 8-inch MEMS international foundry line, Sai Microelectronics will have 8-inch MEMS production lines in Sweden and China at the same time, and the Beijing production line can provide standardized scale production capacity. It is conducive to the company's further expansion of the global market, especially the Asian market, combining advanced technology and scale capacity to better serve downstream customers, while continuing to expand the competitive advantage of the company's MEMS business and maintaining its global leading position in the MEMS pure foundry field.
