台積電3nm產能吃緊「忠誠老客戶」才有拿貨機會

🔑 增強重點摘要

• •TSMC's N3P (3nm enhanced) process node has become the primary driver for high-performance computing (HPC) and AI accelerator demand, leading to a significant shift in wafer allocation strategies toward strategic partners like Apple, NVIDIA, and AMD.
• •The capacity crunch is exacerbated by the transition of major cloud service providers (CSPs) to custom-designed AI silicon, which competes directly with traditional fabless chipmakers for limited 3nm production slots.
• •TSMC has reportedly implemented a 'value-based' pricing model for 3nm capacity, where non-loyal or short-term customers face significant premiums or are deprioritized in favor of long-term capacity reservation agreements.

🛠️ 技術深入

• •TSMC 3nm family utilizes FinFlex technology, allowing designers to mix and match standard cells within the same block to optimize for power, performance, and area (PPA).
• •N3P process node offers approximately 5% speed improvement, 5-10% power reduction, and 1.04x density improvement compared to the base N3E node.
• •The process employs extreme ultraviolet (EUV) lithography with high-NA EUV tools being integrated into subsequent iterations to manage complex patterning requirements for sub-3nm features.
