存算自主可控追赶加速，重视上游设备材料产业链

Summary of Conference Call Records Industry Overview - The conference call primarily discusses the semiconductor industry, focusing on companies such as SMIC (中芯国际), Hua Hong Semiconductor (华虹), Changxin Storage (长鑫存储), and Longsys (长存) [1][2][7]. Key Points and Arguments 1. Expansion of Advanced Processes: SMIC and Hua Hong are expanding their production capabilities for advanced processes below 7nm to meet domestic computing power demands. Hua Hong's expansion at its 8th factory is exceeding expectations, with new production lines expected in 2026. However, some equipment orders for SMIC have been delayed [1][3]. 2. Storage Industry Growth: Changxin Storage and Longsys are expected to see significant upward changes in 2026. Longsys has established its third-phase project focusing on over 300-layer products, with a 30% increase in investment per wafer compared to previous layers. Changxin Storage is also actively expanding and is expected to accelerate its IPO process in 2026 [1][5][6]. 3. HBM Industry Development: The domestic High Bandwidth Memory (HBM) industry is projected to achieve a breakthrough from 0 to 1 in industrialization by 2026. Changxin Storage's Shanghai facility is planning for 3D packaging and HBM production lines, which may create new expansion demands [1][6]. 4. Capital Expenditure Trends: The semiconductor industry's capital expenditure is expected to maintain double-digit growth in 2026, driven by increased domestic production rates and structural changes. Equipment companies may see order growth rates of over 30%, potentially reaching 40%-50% [1][9][10]. 5. Focus on Equipment and Materials: Recommendations for equipment companies include North Huachuang, Zhongwei Company, and Tuo Jing Technology, among others. In the semiconductor materials sector, Anji Technology and Dinglong Co. are highlighted, with domestic semiconductor material demand expected to grow at a compound annual growth rate of 20%-30% [3][12]. 6. Investment Recommendations: For the HBM supply chain, it is suggested to focus on the testing and packaging end, particularly smaller market cap companies like Jingzhida, Xinyuanwei, and Jiaocheng Ultrasonic, which may show significant growth potential [1][8]. Additional Important Insights - The semiconductor industry is showing strong momentum in both logic processes and storage sectors, reflecting increasing market demand and enhancing China's self-sufficiency in semiconductor capabilities [7]. - The investment in equipment for advanced processes is expected to rise significantly, with costs per wafer for 28nm to 7nm processes increasing from approximately 4-5 billion RMB to over 13 billion RMB [4]. - The overall sentiment in the semiconductor sector is positive, with expectations of continued growth and development across various segments [2][7].
