全球半導體TOP10，誰主沉浮

🔑 增強重點摘要

• •Traditional Moore's Law is slowing due to physical limits at sub-2nm scales and escalating fabrication costs, including extreme ultraviolet lithography tools doubling every 4 years[1][3][5].
• •Industry is adopting advanced packaging techniques like 3D stacking (e.g., TSMC’s 3DFabric) and heterogeneous integration to boost performance beyond transistor scaling[2][5].
• •TSMC's 2nm process, marking the 'Angstrom Era,' promises 10-15% performance gains and improved power efficiency over 3nm for AI and high-performance computing[2].
• •Innovations such as optical computing and new transistor designs (e.g., FinFET to gate-all-around) are proposed as potential 'new Moore's Law' paradigms for continued scaling[9][8].

🛠️ 技術深入

• •TSMC’s 2nm process uses gate-all-around (GAA) nanosheet transistors, enabling transistor densities beyond FinFET limits at 3nm[2].
• •3D packaging stacks chips vertically to reduce latency, with TSMC’s 3DFabric integrating logic, memory, and I/O for 20-30% performance uplift without node shrinks[2][5].
• •Extreme ultraviolet lithography (EUV) contributes ~67% to density improvements via optical projection, while optical doping handles the rest[1].
• •Sub-1nm nodes target angstrom-scale gates (e.g., Intel’s roadmap), relying on novel materials to bypass atomic limits[2].
