At present, in various fields such as smart cards, fixed and wireless networks, consumer electronics chips, home appliances, and PC peripheral chips, there are already several integrated circuit (IC) design and manufacturing companies in China. The growth of self-owned brands has been remarkable, with many firms gaining significant market presence.
According to data from the China Semiconductor Industry Association, the sales revenue of the IC design industry in mainland China grew from 2.16 billion yuan in 2002 to 18.6 billion yuan in 2006, representing an average annual growth rate of 71.3%. By 2007, the top five companies in terms of sales were China Huada IC, Shenzhen HiSilicon, Shanghai Spreadtrum Communications, Datang Microelectronics, and Zhuhai Actions IC. These leading local players primarily focus on low-end segments such as smart cards, multimedia, and communication cards. However, during their first few years of operation, these companies experienced rapid business expansion and development.
Looking at some of the major IC design companies in China, we can see a diverse range of players contributing to the industry's growth. While they may not yet dominate the high-end market, their presence is steadily increasing, and they are playing a key role in shaping the future of China's semiconductor industry.
Here are some of the well-known IC design companies in China:
