Global semiconductor silicon wafers have recently seen across-the-board price increases. Leading overseas manufacturers—such as Shin-Etsu, SUMCO, and GlobalWafers—initiated a second round of price hikes, with high-end wafers dedicated to AI computing power seeing increases of 18%–22%. Domestically, prices for heavily doped epitaxial wafers rose by 10%–15%; delivery lead times for wafers of all sizes continue to lengthen, with orders generally booked through the third quarter. This round of price hikes is not merely a short-term correction but marks a long-cycle upward turning point driven by the convergence of multiple factors: surging demand, supply rigidity, domestic substitution, and rising costs. The industry has officially entered a high-growth phase characterized by rising volumes and prices.
I. Five Core Drivers Behind the Significant Rise in Silicon Wafer Prices
1. The AI computing boom generates massive, inelastic demand, creating a significant supply-demand gap for high-end wafers.
AI servers, GPUs, and HBM (High Bandwidth Memory) have become the core incremental drivers of silicon wafer demand. Data shows that AI servers consume 3.8 times the volume of 12-inch wafers compared to standard servers, while HBM consumes three times the wafer volume of conventional DRAM. By 2026, monthly demand for AI-related 12-inch wafers is projected to exceed 1 million units—accounting for over 10% of total global 12-inch wafer demand—leading to acute shortages of heavily doped wafers and specialized high-resistivity wafers. Simultaneously, demand for new energy power semiconductors and automotive-grade chips is rebounding; MOSFETs and IGBTs continue to drive consumption of 8-inch and 12-inch heavily doped epitaxial wafers. Supply falls short of demand across these specific categories, giving manufacturers pricing power.
2. Global supply is highly oligopolistic with extremely long capacity expansion cycles; no new capacity exists in the short term to offset the shortage.
The global high-end silicon wafer market is highly concentrated. Five major overseas giants—Shin-Etsu, SUMCO, GlobalWafers, Siltronic, and SK—control over 75% of the global market share. For high-end 12-inch wafers, this oligopolistic concentration exceeds 85%, resulting in a lack of robust competition on the supply side. Building a silicon wafer production line involves extremely high barriers to entry; a single 12-inch line with a monthly capacity of 100,000 wafers requires an investment exceeding RMB 2.5 billion, with a cycle spanning 18 to 24 months from civil engineering and equipment commissioning to full customer validation. Amid the industry downturn of 2024–2025, major manufacturers slashed capital expenditures; consequently, even with current price hikes, new capacity cannot come online at scale before 2028, and supply rigidity prevents the gap from being bridged.
3. Upstream raw material and energy costs continue to rise, with cost pressures passed down the value chain.
Prices for upstream raw materials—such as quartz sand, specialty electronic gases, and high-purity polysilicon—have steadily climbed throughout the year. Compounded by earlier geopolitical conflicts in the Middle East that drove up energy and chemical prices, the costs of electricity and consumables for wafer manufacturing have risen in tandem. Overseas manufacturers were the first to pass on costs through price hikes; while domestic firms initially absorbed costs and faced profit pressure, they are now raising prices to restore production profitability, establishing a cost-driven foundation for the increases.
4. Overseas giants raise prices in unison, driving a synchronized upward trend across the domestic supply chain.
Starting in May, leading overseas manufacturers issued successive price hike notifications, raising prices for standard 12-inch wafers by 3%–8% and high-end AI-specific wafers by nearly 20%, resulting in a cumulative annual increase exceeding 15%. The rising cost of overseas supplies has significantly increased import expenses for domestic wafer fabs, compelling downstream customers to increase their procurement of domestic wafers. Domestic wafer companies have eliminated previous long-term discounts and are gradually raising spot and long-term contract prices, creating a synchronized price-hike trend across domestic and international markets.
5. Domestic substitution accelerates as downstream wafer fabs proactively switch to local suppliers, unleashing increased demand for domestic wafers.
Driven by supply chain security needs, domestic companies—including SMIC, Hua Hong, and memory manufacturers—are accelerating the adoption of domestic wafers. The localization rate for 12-inch wafers is projected to rise from 15%–20% in 2025 to 25%–30% in 2026, leading to a substantial increase in orders for local wafers. Domestic production capacity remains fully utilized with backlogged orders, further bolstering the confidence of domestic wafer companies to raise prices. II. Underlying Logic for Sustained Industry Prosperity: Long-Cycle Resonance of Dual Demands (Computing Power + New Energy)
Long-term expansion of the AI computing industry raises the growth ceiling for silicon wafers
The global build-out of computing power for large models, data centers, and autonomous driving continues to accelerate, driving a long-term upward trend in demand for computing and memory chips. Demand for high-end 12-inch silicon wafers is growing at an annualized rate of 20%–30%, serving as the industry's core growth driver; this demand cycle is expected to last at least 3–5 years, with no risk of short-term decline.
Demand for automotive-grade and power semiconductors in the new energy sector provides a stable floor
New energy vehicles, photovoltaic inverters, and energy storage systems are driving a sustained recovery in demand for power devices. Stable, essential demand for 6-inch and 8-inch heavily doped epitaxial wafers forms a second growth pillar. Meanwhile, the consumer electronics sector has largely completed inventory destocking, and demand for analog and CIS chips is showing signs of marginal recovery, helping to buffer against industry volatility.
Industry cycle rebounds from the bottom; corporate profitability steadily recovers
After a period of sustained losses and high inventory levels in 2024–2025, the supply-demand landscape underwent a complete reversal in 2026. Leading companies are operating at 98%–100% capacity utilization. Rising volumes and prices have triggered an industry-wide profitability inflection point, while capital expenditure and R&D investment are rebounding in tandem, creating a virtuous cycle that supports continued industry prosperity.
Global supply chain restructuring creates vast long-term potential for domestic silicon wafer substitution
Amidst geopolitical trade tensions, chip manufacturers worldwide are diversifying supply chains to reduce reliance on single overseas sources. Domestic silicon wafer companies have achieved rapid technological breakthroughs and are increasingly entering the supply chains of global customers; this offers significant long-term substitution potential and generates continuous incremental demand for the industry.
III. Current Status of Production Capacity and Output for Domestic Enterprises
1. Capacity Scale and Layout
A tier of leading domestic silicon wafer enterprises has emerged, anchored by companies such as NSIG (Shanghai Simgui), Zhonghuan Leading, and Lion Micro. Planned total capacity for 12-inch silicon wafers nationwide exceeds 7 million wafers per month, with capacity currently under construction or in the production ramp-up phase steadily coming online. The combined 12-inch wafer capacity at the two core bases in Shanghai and Taiyuan has reached 750,000 wafers per month, placing them in the top tier of domestic producers. Production capacity for 8-inch and 6-inch silicon wafers is well-established, while dedicated production lines for specialized wafers—such as heavily doped epitaxial wafers and SOI wafers—are undergoing continuous expansion to address domestic capacity gaps in these niche segments.
2. Production Volume and Capacity Utilization
Capacity utilization rates at major domestic and international silicon wafer plants remain high; leading companies are operating their 12-inch lines at full capacity with 24-hour, three-shift production schedules, and there are no plans for large-scale maintenance or production cutbacks. Capacity for heavily doped silicon wafers is tight, with some companies reducing spot market supplies to prioritize the fulfillment of long-term orders; while capacity for lightly doped general-purpose wafers is relatively ample, robust orders from downstream foundry clients keep inventory levels consistently low.
In terms of shipment composition, domestic companies have seen a year-on-year increase of over 40% in 12-inch wafer shipments and over 25% in 8-inch epitaxial wafer shipments. Their product portfolios now span the full spectrum of logic, memory, power, and RF applications, with a continuing shift toward higher value-added products.
3. Capacity Constraints and Shortcomings
Gaps remain in the capacity for high-end 12-inch polished wafers, ultra-thin epitaxial wafers, and SOI wafers. Reliance on imports for core precision equipment and high-purity consumables limits the large-scale ramp-up of high-end products in the short term. Meanwhile, small and medium-sized manufacturers face limited financial resources and slower expansion paces compared to industry leaders, leading to continued industry consolidation around top-tier players.
IV. Directions for Technological Innovation and Development
Continued Breakthroughs in High-End Silicon-Based Materials
Domestic companies are increasing R&D investment, focusing on key technologies such as 300mm ultra-thin wafers, ultra-low resistivity heavily doped wafers, SOI wafers, and silicon carbide composite substrates. Numerous new products have passed certification by leading global chip manufacturers, enabling volume supply for AI computing, RF radar, and automotive-grade power devices. Leading companies develop over 50 new silicon wafer products annually, with a cumulative total of more than 800 certified specifications covering mainstream global application scenarios.
Upsizing and Evolution of Wafer-Thinning Processes
The industry continues to advance the transition to larger wafer sizes, with 12-inch wafers gradually replacing 8-inch wafers as the mainstream standard. Continuous optimization of wafer-thinning and low-defect polishing processes reduces manufacturing losses, meets the production requirements of advanced-node chips, and narrows the technological gap with overseas industry giants.
Innovation in Green and Low-Carbon Manufacturing Processes
The industry is promoting low-energy crystal growth, water recycling systems, and production lines powered by green energy to align with EU carbon tariffs and global low-carbon procurement standards. Green wafers have become a competitive advantage for overseas procurement, enhancing the global competitiveness of domestic products.
Upgrading of Customized Support Services
Enterprises are integrating precision processing, testing, and epitaxial services alongside wafer production. By securing long-term agreements with downstream wafer fabs, they increase customer loyalty; meanwhile, differentiated innovation helps alleviate the pressure of commoditized competition associated with standard wafers.
V. Overview of the Global Overseas Market
Overseas Supply Landscape: Oligopolistic Control and Unified Intent to Raise Prices**
The five major overseas wafer manufacturers are strictly controlling capacity expansion, prioritizing supply to domestic and Western high-end chip clients, and tightening export quotas for high-end wafers to China. Due to capital expenditure constraints, no large-scale capacity additions are expected in the next two years, leading to a sustained tight balance in the global high-end wafer market. The overseas market shows clear segmentation: high-end computing chip manufacturers in Europe and the US are locking in AI-specific wafers at premium prices, while manufacturers of mature-node chips in Southeast Asia and South Korea are competing for supplies of standard 8-inch and 12-inch wafers.
Divergence in Overseas Demand Structure
Demand for AI computing chips is surging in North American and European markets, driving up premiums for high-end wafers. Demand for mature-node and memory chips in Japan and South Korea remains stable. Meanwhile, wafer foundry capacity in Southeast Asia continues to expand, leading to rising annual import demand for wafers and making the region a key growth market globally.
Global Trade Barriers and Supply Chain Restructuring
Many countries have introduced policies to localize chip supply chains and reduce reliance on single-region sources. Europe and the US have implemented carbon tariffs and support policies for local capacity, raising entry barriers for foreign products. Simultaneously, downstream overseas manufacturers are actively onboarding secondary and tertiary suppliers, creating opportunities for Chinese wafer companies to capture market share through import substitution. Shortcomings of Overseas Competitors Become Apparent
Overseas manufacturers face long capacity expansion and delivery cycles. Some small and medium-sized overseas chipmakers, struggling to secure sufficient long-term agreement (LTA) quotas, are turning to more cost-effective domestic silicon wafers, leading to a steady rise in the global market share of domestic products.
VI. Status of Overseas Orders for Domestic Silicon Wafer Enterprises
