Investment Rating - The report maintains a "Buy" rating for the semiconductor testing equipment industry, indicating a favorable outlook for investment opportunities in this sector [1]. Core Insights - The semiconductor testing equipment industry is experiencing a critical phase characterized by "value reassessment, demand surge, and accelerated domestic substitution," which presents significant investment opportunities [5][6]. - The testing equipment is essential throughout the semiconductor manufacturing process, with ATE (Automatic Test Equipment) leading in value contribution, while probe stations and handlers work in synergy to enhance testing efficiency [11][20]. - The demand for testing equipment is driven by three main factors: AI computing power, advanced packaging, and automotive electronics, which collectively create a favorable environment for growth [5][6]. Summary by Sections 1. Testing Equipment's Role in Manufacturing - Semiconductor testing equipment is a core component of the integrated circuit industry, covering wafer testing, packaging testing, and functional verification [11]. - Testing occurs in two main phases: Circuit Probing (CP) and Final Test (FT), which are crucial for ensuring product quality and cost efficiency [11][15]. 2. Demand Drivers - The complexity of AI computing chips is increasing, leading to longer testing cycles and higher equipment demand [6]. - Advanced packaging techniques are creating new testing requirements, such as KGD (Known Good Die) and SLT (System Level Test), which further drive the need for testing equipment [6]. - The automotive sector is also contributing to demand growth, with a significant increase in the number of chips required for smart vehicles, necessitating rigorous testing standards [5][6]. 3. Global Market Dynamics - The testing equipment market is dominated by a few key players, particularly in the ATE segment, where companies like Advantest and Teradyne hold over 90% market share [5][6]. - The report highlights the importance of platform integration and vertical consolidation as strategies for leading companies to maintain competitive advantages [5][6]. 4. Domestic Substitution Opportunities - The report identifies a clear path for domestic manufacturers to increase their market share, particularly in the SoC and storage testing segments, where current domestic production rates are low [5][6]. - Companies such as Changchuan Technology, Huafeng Measurement Control, and Xidian Co. are highlighted as key players with potential for growth in the domestic market [5][6].
