domestic semiconductor industry has made remarkable progress in recent years, with China's chip market size reaching a record high of over 400 billion yuan in 2022.

The top five Chinese chip manufacturers accounted for more than half of the country's total output, led by SMIC, Huawei HiSilicon, Yangtze Memory Technologies Co., Ltd., Tsinghua Unigroup and Hua Hong Semiconductor.

SMIC is currently China's largest independent integrated circuit design company and the world's second-largest independent IC foundry service provider after Taiwan Semiconductor Manufacturing Company (TSMC). In addition to its core business of producing high-end chips for smartphones and automobiles, it also provides customized services for other companies.

Huawei HiSilicon is a subsidiary of Huawei that focuses on developing advanced communication technologies such as 5G base stations and smartphone processors. Despite facing significant challenges due to US sanctions against Huawei, the company continues to invest heavily in research and development.

Yangtze Memory Technologies Co., Ltd., a leading memory chip manufacturer based on the Shanghai Free Trade Zone, has developed cutting-edge NAND flash memory technology using its proprietary three-dimensional stacked structure design method called "Xiangxiang". This innovative approach has significantly improved storage density while reducing power consumption compared to traditional two-dimensional designs.

The rapid growth of China's semiconductor industry reflects not only technological advancements but also government support policies aimed at promoting indigenous innovation capabilities and reducing dependence on foreign suppliers. With ongoing investments in R&D facilities and talent recruitment programs, this sector is expected to continue driving economic transformation across various industries within China while contributing substantially to global competition in the field of semiconductors.
