Group 1 - The core viewpoint is that the capacity utilization rate of foundries is expected to remain stable due to low inventory levels among chip design companies, the peak sales season for smartphones, and strong ongoing demand for AI [1] - Some foundries are considering price increases for tight process platforms such as BCD and Power due to better-than-expected performance in Q4 compared to Q3 [1] - The importance of domestic foundries is highlighted by the surge in demand for advanced foundry services driven by domestic computing infrastructure and the "China for China" strategy [1] Group 2 - According to SEMI, the CAGR for Chinese wafer fabs from 2024 to 2028 is projected to be 8.1%, surpassing the global average of 5.3% [2] - The CAGR for mature nodes (55nm and above) in China is expected to be 3.7%, while mainstream nodes (22nm-40nm) will see a CAGR of 26.5%, and advanced nodes (14nm and below) will have a CAGR of 5.7% [2] - By 2024, China's mainstream node capacity is expected to account for 25% of the global total, increasing to 42% by 2028 [2] Group 3 - Major domestic foundries include SMIC, Hua Hong Semiconductor, Jinghong Integrated Circuit, Yandong Microelectronics, and ChipLink Integrated [3]
