【环球网财经综合报道】2020年以来，以国家大基金、税收优惠等政策为支撑，叠加外部技术封锁与国 内晶圆厂扩产需求拉动，我国半导体行业国产化进度逐步从单点突破迈向全链协同。 综合中国半导体行业协会 (CSIA)、赛迪顾问 2025 年半导体产业发展报告数据，28nm及以上成熟制程率 先实现国产化，自给率达60%；刻蚀、清洗、薄膜沉积等设备及8英寸硅片等材料国产化率突破50%， 先进封装在Chiplet等领域达国际先进水平，长江存储、长电科技（600584.SH）等龙头企业崛起。上述 各环节取得的成果使得整体国产化率从2020年不足20%提升至2025年45%左右，芯片出口于2024年成为 我国第一大出口商品，自主可控能力显著增强。 在此背景下，未来几年伴随我国半导体产业向5nm/3nm等先进制程加速突破的确定性趋势，受益于在产 能、效率及良率几个关键指标方面均可以发挥关键作用，AMHS（自动物料搬运系统）已从历史阶段的 辅助工具升级为决定先进制程可行性的核心基础设施。 AMHS 应用贯穿从硅片投入到出厂制造全流程 根据公开资料，AMHS即自动物料搬送系统，一般特指在洁净室环境下，通过软件系统的控制和调度， 按照 ...

Investment Rating - The investment rating for the cleanroom industry is "Positive" and maintained [11] Core Viewpoints - The cleanroom sector is currently in a phase of marginal improvement, with ongoing domestic and international project releases, leading to a potential acceleration in orders for related companies and sustained growth in performance [3][32] Summary by Sections Upstream Equipment - Air filtration systems, including various types of filters and purification devices, are critical solutions designed for semiconductor clients. Major international brands include AAF and Camfil, while domestic players include Meier Technology and Youyuan Environment [7][35] - The global AMHS (Automated Material Handling System) market accounts for approximately 3% of the semiconductor equipment total, with expectations for the Chinese AMHS market to exceed 10 billion yuan by 2025. The market has been historically dominated by Japanese companies Daifuku and Murata Machinery, which hold over 90% market share [7][47][49] Cleanroom Engineering - The competitive landscape for cleanroom engineering is stable, with leading design and general contracting firms such as Shiyi Technology and Shiyuan Technology establishing strong market positions. Shiyi Technology has unique expertise in high-level purification systems for semiconductor and biopharmaceutical environments [8][52] - Major players in the cleanroom engineering subcontracting market include Shen Sanda A, Shenghui Integration, and Yaxiang Integration, all of which have significant market shares and experience in high-end cleanroom projects [8][65] Downstream Capital Expenditure - Since mid-2022, companies like Shenghui and Yaxiang have seen significant stock price increases, driven by growth in semiconductor projects. Shenghui's uncompleted project scale reached 47 billion yuan, a 44% increase, while Yaxiang's cumulative orders surged to 208.49 billion yuan, with 63% from semiconductors [9][88] - The cleanroom industry is expected to benefit from ongoing overseas expansions in Southeast Asia and North America, as well as domestic projects driven by local replacements. Key projects include the Shanghai Xinpux Tianying project and the AMOLED 8.6 generation line by Visionox [10][60]
