供应链安全事件催化，半导体材料/设备自主可控有望提速

Core Viewpoint - The semiconductor industry is experiencing a dual-driven investment logic due to heightened external risks and internal capacity expansion, leading to accelerated self-sufficiency in semiconductor materials and equipment [2][4]. Group 1: External Risks and Market Dynamics - Increasing geopolitical risks are prompting a reevaluation of reliance on foreign technology, particularly in critical supply chain segments [2][3]. - The recent ban on dual-use items to Japan is expected to enhance domestic manufacturers' willingness to adopt local solutions, especially in "bottleneck" areas [2][4]. Group 2: Investment and Capital Movements - Recent capital movements include Longxin's IPO aiming to raise approximately 30 billion yuan, SMIC's Southern factory increasing investment by over 7 billion USD, and the Big Fund increasing its stake in SMIC, indicating a comprehensive acceleration in capital layout [2][3]. - The integration of mature logic rights by major fab plants signifies a robust long-term fundamental outlook for the industry [2]. Group 3: Material and Equipment Developments - Domestic materials have transitioned from "single-point breakthroughs" to a "systematic support" phase, with a focus on high-end photolithography materials where domestic production remains low [3][4]. - Key domestic material leaders are proactively building capacity to meet future order demands, ensuring alignment with downstream production needs [3]. Group 4: Beneficiary Companies - Beneficiary companies in materials include Tongcheng New Materials, Jingrui Electric Materials, Nanda Optoelectronics, and others, while in equipment, companies like Changchuan Technology and ChipSource Micro are positioned to benefit from the evolving landscape [5].
