Semiconductor Industry Research Summary Industry Overview - The semiconductor industry exhibits a decreasing profitability trend across its value chain, with IC design being the most profitable, followed by wafer manufacturing, and equipment and materials being relatively lower in profitability [1][4] - The semiconductor manufacturing process is divided into front-end (80% value) and back-end processes (20% value), with front-end processes including diffusion, thin film deposition, lithography, and etching, while back-end processes involve wafer packaging [1][5] - The global semiconductor equipment market is approximately $100 billion, characterized by cyclical growth that fluctuates with semiconductor demand [1][10] Key Trends and Developments - The transition from 2D to 3D chip structures is increasing transistor density and complexity, driving capital expenditure [1][8] - Advanced processes significantly increase equipment demand, with capital expenditure density rising sharply; for instance, the capital expenditure for 7nm process is about $1.2 billion per 10,000 wafers, while for 5nm it reaches $8.3 billion per 5,000 wafers [9][11] - The semiconductor industry is highly concentrated, with the top five companies holding nearly 80% of the market share, including ASML, Applied Materials, Lam Research, Tokyo Electron, and KLA [13][15] Market Dynamics - The demand for semiconductor equipment is expected to remain robust, with China’s semiconductor equipment procurement projected to exceed $40 billion in 2025 and 2026 [3][18] - The domestic semiconductor equipment companies in China are benefiting from increased demand for self-sufficiency, with a low domestic production rate in lithography machines (below 5%) but higher rates in materials [3][19][16] - The semiconductor materials market is valued at over $60 billion, with wafer manufacturing materials accounting for approximately $42.9 billion and packaging materials around $24.6 billion [20] Investment Opportunities - The semiconductor materials sector offers advantages due to its continuous and cumulative demand, which is less affected by cyclical fluctuations compared to equipment manufacturing [21] - The current phase of expansion and increased self-sufficiency in the domestic semiconductor industry presents significant investment opportunities, particularly in advanced processes [22] - Despite some market segments being overheated, semiconductor equipment and materials remain undervalued, indicating a potential growth of about 30% from a valuation perspective [22]

Investment Rating - The investment rating for the company is "Buy" (maintained) [7] Core Views - The company is positioned as a leading domestic wafer foundry, with the explosive demand for domestic AI chips and the trend of localization in edge-side chips expected to drive its performance growth beyond expectations [1][3] Demand and Supply Analysis - Demand Side: The growth in the AI cloud server industry is expected to drive the demand for AI chips. Additionally, domestic cloud manufacturers are increasingly seeking to localize AI chip production, which will further stimulate demand. There is potential for elasticity in advanced process wafer consumption if certain brands experience an upward turning point in sales expectations [3] - Supply Side: Domestic semiconductor equipment is being customized to better fit local process routes, which may lead to an unexpected improvement in wafer foundry yield rates. The long-term trend in the wafer foundry industry is expected to favor larger players, and the company is likely to benefit from the localization of advanced processes and the demand surge in the AI chip sector [3] Driving Factors - The explosive demand for AI chips in both cloud and edge markets is expected to create significant opportunities for advanced process expansion [4] Performance Metrics and Catalysts - Key performance indicators include the shipment pace of domestic AI chips and discrepancies between performance guidance and actual results. Catalysts for growth include orders for key production line equipment, breakthroughs in critical process yields, and accelerated localization in IC design tape-outs [5] Financial Forecast and Valuation - The company is projected to experience a new phase of revenue and profit elasticity from 2025 to 2027, with expected net profits of 5.352 billion, 6.370 billion, and 7.456 billion respectively, representing year-on-year growth rates of 44.7%, 19.0%, and 17.0%. The estimated P/B ratios for the same period are 4.5, 4.3, and 4.1, while the P/E ratios are 135.8, 114.1, and 97.5 [6][12]
