TSMC 3nm產能吃緊，預計2026下半年價格上漲15%

🔑 增強重點摘要

•TSMC's 3nm capacity is reportedly booked through 2028, indicating a sustained period of high demand and limited supply for its most advanced nodes.
•Major customers like Nvidia have been forced to adjust their production strategies, reportedly scaling back orders for their next-generation 3nm AI chips (Rubin Ultra) and increasing reliance on 4nm chips (Blackwell) due to TSMC's 3nm capacity constraints.
•TSMC's 3nm process (N3) continues to utilize FinFET transistor technology, distinguishing it from Samsung's 3nm process which adopted Gate-All-Around (GAAFET) technology.
•The high demand and TSMC's pricing power are partly attributed to its superior 3nm production yields, which are reported to exceed 90%, significantly higher than Samsung Foundry's 3nm yields, which have hovered around 50% or even 20% for its second-generation process.
•TSMC is actively expanding its 3nm production footprint globally, with new fabrication facilities planned or under construction in Taiwan, Arizona (USA), and Kumamoto (Japan), to address the overwhelming demand for advanced chips.

🛠️ 技術深入

TSMC's 3nm process (N3) is a full-node advancement over its 5nm generation, offering significant improvements in performance, power, and area.
Compared to the 5nm process, N3 is projected to deliver a 10-15% increase in performance or a 25-35% decrease in power consumption.
It achieves a 70% increase in logic density, a 20% increase in SRAM cell density, and a 10% increase in analog circuitry density over N5.
The N3 process utilizes FinFET (Fin Field-Effect Transistor) technology, which is expected to be TSMC's last node employing this architecture before transitioning to nanosheet (GAAFET) technology for its 2nm node.
Manufacturing at 3nm requires extensive use of multipatterned Extreme Ultraviolet (EUV) lithography, with N3 using over 20 EUV layers.
TSMC has developed several variants of its 3nm process family, including N3E (Enhanced), N3P (Performance-enhanced), N3X (optimized for High-Performance Computing with higher clock speeds), N3C (cost-effective), and N3A (automotive applications).
The N3E variant, for instance, is slightly faster and more power-efficient than the original N3, though it may offer reduced density gains due to single-patterning some layers to lower manufacturing costs.
TSMC's FinFlex technology allows for intermixing cells with different numbers of fins within a single chip, providing design flexibility for power, performance, and area optimization.
Projected transistor density for TSMC's 3nm chips is nearly 300 million transistors per square millimeter.

The price hike will likely accelerate the development and adoption of alternative manufacturing strategies by major chip designers.

With TSMC's 3nm prices rising and capacity remaining tight, customers may invest more in co-development with other foundries or explore advanced packaging solutions to integrate chips from different nodes and suppliers.

TSMC's dominant position in advanced node manufacturing will be further solidified in the short to medium term.

Despite price increases, TSMC's superior yields and established production capabilities at the 3nm node give it a significant competitive advantage over rivals like Samsung, who continue to face yield challenges.

The intense demand for AI chips will continue to be a primary driver for TSMC's capacity expansion and technological advancements.

The ongoing AI boom is the main factor straining TSMC's 3nm capacity, prompting the company to invest heavily in new fabs and advanced packaging technologies to meet the robust multi-year pipeline of AI-related demand.
