In recent years, China has faced significant challenges in the semiconductor industry due to reliance on critical equipment like photolithography machines, which have become a major ‘choke point.’ To overcome this technological blockade, Chinese research institutions and companies are actively exploring alternative chip manufacturing approaches. Key strategies include chiplet (Chiplet) technology, heterogeneous integration, and advanced packaging-based ‘More-than-Moore’ pathways. For instance, Tsinghua University has developed a ‘lithography-free’ nanoimprint technique, while Huawei and the Chinese Academy of Sciences are advancing 3D stacking and silicon photonics integration—both reducing dependence on high-end lithography tools. Additionally, China is investing in next-generation chips based on carbon-based and two-dimensional materials, aiming for a fundamental architectural leap. Although these innovations have not yet fully replaced conventional silicon-based CMOS processes, they offer promising alternatives and strategic breathing room for building an independent and controllable semiconductor supply chain. With continued progress in materials science, packaging technologies, and design methodologies, China may carve out a distinctive path in the global chip competition.
近年来，中国在半导体领域面临光刻机等关键设备被‘卡脖子’的严峻挑战。为突破这一技术封锁，国内科研机构与企业积极探索新型芯片制造路径。其中，芯粒（Chiplet）技术、异构集成、以及基于先进封装的‘超越摩尔’路线成为重要突破口。例如，清华大学团队开发的‘无光刻’纳米印刷技术，以及华为、中科院等推动的3D堆叠与硅光集成方案，均在一定程度上绕开了对高端光刻机的依赖。此外，中国还在发展基于碳基材料、二维材料等新物理体系的芯片，试图从底层架构实现换道超车。这些创新虽尚未完全替代传统硅基CMOS工艺，但为构建自主可控的半导体产业链提供了新思路和战略缓冲期。未来，随着材料科学、封装技术和设计方法的协同进步，中国有望在全球芯片竞争格局中开辟独特路径。
