While the global semiconductor industry is intensely focused on the race toward cutting-edge nodes like 3nm and 2nm, Japanese companies have chosen a different path—shifting away from blindly chasing the most advanced process technologies and instead concentrating on specialty processes, mature nodes, and high-reliability solutions. This strategic pivot stems from multiple factors: on one hand, the soaring R&D costs and technical barriers of advanced nodes make sustained investment challenging for Japan’s relatively smaller foundries; on the other, Japan has deep expertise in automotive electronics, industrial control, sensors, and power semiconductors—sectors where chip requirements prioritize stability, durability, and customization over raw transistor density.For instance, Renesas Electronics and Sony are heavily investing in mature-node production lines (40nm to 90nm) to manufacture automotive MCUs and image sensors. Meanwhile, the Japanese government supports this approach through its ‘Semiconductor Revitalization Strategy,’ offering subsidies to strengthen domestic supply chains and foster differentiated competitiveness. This ‘beyond-Moore’ strategy not only reduces reliance on expensive equipment like EUV lithography machines but also secures Japan a unique and indispensable role in the global semiconductor ecosystem. As the world increasingly recognizes that advanced nodes aren’t a panacea, Japan’s pragmatic approach may well become a key paradigm in the post-Moore era.
在全球半导体产业高度聚焦于3纳米、2纳米等先进制程竞赛的背景下，日本企业选择了一条与众不同的发展路径——不再盲目追逐最尖端工艺节点，而是专注于特色工艺、成熟制程与高可靠性技术。这一战略转变源于多重因素：一方面，先进制程研发成本高昂、技术门槛极高，对日本相对规模较小的晶圆厂而言难以持续投入；另一方面，日本在汽车电子、工业控制、传感器和功率半导体等领域拥有深厚积累，这些应用对芯片性能的要求更侧重稳定性、耐用性与定制化，而非单纯追求晶体管密度。例如，瑞萨电子（Renesas）和索尼（Sony）正大力投资于40纳米至90纳米的成熟制程产线，用于生产车用MCU和图像传感器。同时，日本政府也通过‘半导体复兴战略’提供补贴，鼓励本土企业强化供应链安全与差异化竞争力。这种‘非摩尔定律’路线不仅降低了对EUV光刻机等昂贵设备的依赖，也使日本在全球芯片生态中找到了不可替代的定位。长远来看，当全球市场逐渐意识到先进制程并非万能解药时，日本的务实策略或将成为后摩尔时代的重要范式。
