2025-07-28 01:42Summary of Conference Call Notes Industry Overview - The discussion focuses on the advanced semiconductor manufacturing industry, particularly in relation to autonomous driving and robotics, and their impact on wafer fabrication capacity [1][2][5]. Key Points and Arguments 1. Demand for Advanced Process Capacity - The combined demand for autonomous driving and robotics is estimated at 1.65 million wafers per month, equivalent to the capacity of approximately 3.25 TSMC facilities. Domestic wafer fabs would need to increase their capacity by 37 times to meet this demand [1][5]. 2. Comparison of Chip Types - The die size of autonomous driving and robotics chips is similar to that of GPUs, leading to comparable capacity consumption. However, the market size for autonomous driving and robotics is significantly larger, indicating a greater demand for advanced process capacity [2][3][4]. 3. NVIDIA's Cost Structure - In NVIDIA's data center business, the value allocated to wafer foundry services is very low, accounting for only 2.25% of sales. The breakdown shows that HBM contributes 7.25% and packaging costs account for 5.5% [6][10]. 4. Future Capacity Needs - The future demand for advanced process capacity from autonomous driving and robotics is expected to surpass that of AI GPUs. As penetration rates increase, the demand for chips in these sectors could grow significantly, potentially exceeding tenfold [3][17][20]. 5. Challenges for Domestic Foundries - Domestic advanced foundries face challenges in producing high-end chips due to a lack of EUV lithography machines, leading to lower yields compared to TSMC. For instance, TSMC achieves a 50% yield with single exposure, while domestic foundries using multiple exposures see significantly reduced yields [15][16]. 6. Market Dynamics - The structure of customers for advanced process foundries is expected to change as the demand from autonomous driving and robotics increases. This shift will require more resources to be allocated to these emerging fields [7][22]. 7. Investment Considerations - Investors should focus on the expansion plans of advanced process foundries, as the demand for wafer consumption is expected to rise significantly. Companies like TSMC and SMIC, which have linear growth expansion plans, should be prioritized [23]. Additional Important Insights - The potential for robots to consume wafer capacity is substantial, with predictions suggesting a global demand for 1.51 million wafers for robotics by 2040, far exceeding the demand for autonomous driving chips [20]. - The trend of "one car, multiple chips" is becoming common in new vehicle designs, indicating a growing need for more advanced chips in automotive applications [18]. - The current consumption of wafer capacity is dominated by smartphones, computers, and tablets, but this is expected to shift as autonomous driving and robotics gain traction [21][22].
