The company's main products are various power electronic device chips, power diodes, rectifier bridges, high-power modules, small signal diodes, triodes, MOSFETs, IGBTs and silicon carbide SBDs, silicon carbide JBS, etc. The products are widely used in 5G, power electronics, consumer electronics, security, industrial control, automotive electronics, new energy and many other fields.

SMIC: SMIC is the largest wafer factory in mainland China and ranks fourth in the global pure wafer foundry field. It plays a pivotal role in China's chip industry chain.

The company continues to accelerate technology research and development, establish key platforms and strategic alliances, and is committed to becoming a world-class mainstream patch processing factory.

The company provides one-stop services. In addition to integrated circuit wafer foundry, it also provides complete supporting services in design services and IP support, photomask manufacturing, bump processing and testing. The advanced level is leading in China and covers most downstream applications.

Sanan Optoelectronics: It is mainly engaged in the research and development, production and sales of full-color ultra-high brightness LED epitaxial wafers, chips, III-V compound semiconductor materials, microwave communication integrated circuits and power devices, optical communication components, etc. The company's traditional visible light business has developed rapidly, LED production capacity has continued to expand, and it has followed the development trend of the SMT patch industry and actively laid out new application areas such as Mini LED and Micro-LED.

In addition, the company actively promotes the layout of invisible light business, steadily promotes the verification of domestic and foreign customers of gallium arsenide PA and gallium nitride power electronic integrated chips, and further promotes the layout of optical communication and filter business. Traditional business and emerging business go hand in hand to consolidate the company's leading position in the industry.

Silan Micro: Silan Micro is definitely a well-deserved integrated circuit leader. Although its market value is not the largest and its increase is not the highest, when it comes to integrated circuit products, it is definitely a well-deserved leader in domestic integrated circuits. The company is a leading enterprise in China's integrated circuit PCB design industry. The technology it has mastered and possesses can be used to develop mid-to-high-end products. Its core technology is at a high level among its peers in China and has obvious competitive advantages.

North Huachuang: The company is mainly engaged in the research and development, production, sales and technical service of basic electronic products. Its main products include semiconductor equipment and components such as etcher, physical vapor deposition equipment, chemical vapor deposition equipment, oxidation furnace, diffusion furnace, cleaning machine and lithium electrode sheet equipment.

Sugon: Sugon was established in 2006. It is a high-tech enterprise incubated on the basis of major national scientific research results and promoted by key national scientific and technological institutions such as the Ministry of Science and Technology and the Chinese Academy of Sciences. Its main business is the research and development and manufacturing of high-performance computers and storage devices, as well as supporting systems, software and other technical services. Whether it is the shareholder background or the technical background, the starting point is quite high.

Changdian Technology: A world-renowned transistor manufacturer and a leading domestic enterprise in integrated circuit packaging and testing. The leader of domestic packaging and testing, Changdian Technology is present in all high-end, medium-end and low-end markets. A global leading semiconductor microsystem integration and packaging and testing service provider, providing a full range of one-stop microsystem integration services.

Beijing Ingenic: One of the top ten IC design companies with the greatest development potential in China, it is one of the very few companies in China that has independent innovative CPU core technology, and is the largest domestic supplier of self-designed embedded CPU chips.

Unigroup Guoxin: The company's memory chip business is deeply rooted in the application needs of domestic computers.
