Panorama of Asian Semiconductor Q2 Capacity Utilization: AI and Automotive Chips Drive Growth, Mature Processes Lead Recovery
In Q2 2026, Asia's semiconductor industry shows a clear pattern of differentiated capacity utilization. With sustained high demand for AI chips and recovery in the automotive electronics market, overall industry capacity utilization has steadily improved, though performance varies across different segments. Mature processes are leading the recovery, while capacity constraints in advanced processes have eased, a trend that is reshaping the Asian semiconductor industry landscape.
Overall Capacity Utilization Performance: Structural Recovery Trend Established
According to the latest industry data, average capacity utilization at major Asian semiconductor manufacturers reached 82.3% in Q2 2026, an increase of 3.7 percentage points from the previous quarter and 5.2 percentage points from the same period last year. This data indicates that after more than two years of adjustment, the Asian semiconductor industry has entered a new recovery cycle.
From a regional perspective, Taiwan has the highest semiconductor capacity utilization at 85.6%, mainly benefiting from capacity expansion at foundries like TSMC and UMC. South Korea follows with 83.2%, with memory chip giants Samsung Electronics and SK Hynix both achieving utilization rates above 85%. Mainland China's capacity utilization was 78.5%, with significant recovery in capacity utilization at mature process manufacturers such as SMIC and Huahong Semiconductor. Japan and Southeast Asia recorded 76.8% and 74.3% respectively, still in the recovery phase.
Segment Differentiation: AI and Automotive Chips Lead Growth
In terms of segments, AI-related chips showed the most impressive capacity utilization. Taking TSMC's CoWoS advanced packaging capacity as an example, utilization reached an astonishing 97.8% in Q2 2026, an increase of 2.3 percentage points from the previous quarter. AI chip designers like NVIDIA and AMD continue to expand order volumes, driving sustained tightness in advanced packaging capacity.
Automotive chip sector also showed strong performance, with average capacity utilization reaching 89.5%, an increase of 4.8 percentage points from the previous quarter. With the continuous increase in new energy vehicle penetration and upgrades in intelligent driving features, demand for automotive-grade MCUs, power devices, sensors and other chips remains strong, with automotive chip manufacturers like NXP, Renesas, and Infineon all achieving utilization rates above 90%.
In contrast, recovery in capacity utilization for consumer electronics-related chips has been relatively slow. Demand for traditional terminals like smartphones and PCs is still recovering, with related chip capacity utilization at only 75.2%, an increase of 2.1 percentage points from the previous quarter but still at a low level.
Mature vs. Advanced Processes: Divergent Fortunes
In Q2 2026, mature processes (28nm and above) achieved a capacity utilization rate of 86.5%, an increase of 4.3 percentage points from the previous quarter, becoming the main driver of this recovery. This trend is mainly driven by the widespread application of mature processes in automotive electronics, industrial control, IoT and other fields.
Manufacturers focused on mature processes, such as SMIC and UMC, showed particularly significant recovery in capacity utilization. SMIC's Q2 capacity utilization reached 88.7%, an increase of 5.2 percentage points from the previous quarter; UMC's capacity utilization reached 87.3%, an increase of 4.8 percentage points. Both companies reported that demand for mature processes has returned to healthy levels, with some product lines even experiencing supply shortages.
Meanwhile, capacity utilization for advanced processes (7nm and below) has decreased slightly but remains at high levels. TSMC's 7nm and 5nm processes achieved capacity utilization rates of 94.2% and 96.5% respectively, with 3nm process utilization reaching 91.8%. The easing of capacity constraints in advanced processes is mainly due to AI chip designers expanding capacity while also optimizing product portfolios and increasing adoption of mature processes.
Inventory Cycle Turning Point: Destocking Effects Visible
In Q2 2026, the semiconductor industry's destocking efforts have shown significant results, with inventory turnover days decreasing to 68, a reduction of 9 days from the previous quarter and approaching healthy industry levels. This change has created favorable conditions for the improvement of capacity utilization.
The destocking effect is most pronounced in the memory chip sector, with DRAM inventory turnover days falling to 65 and NAND Flash to 72, both within reasonable ranges. Samsung Electronics and SK Hynix both reported that memory chip inventory has returned to normal levels, with some products even experiencing supply shortages.
The main drivers of destocking include recovering terminal demand, manufacturers actively adjusting production strategies, and supply chain management optimization. As inventory levels return to healthy levels, the semiconductor industry is expected to enter a new growth cycle.
Comparison of Major Enterprise Capacity Performance
In the foundry sector, TSMC achieved a capacity utilization rate of 93.5%, with 3nm and 5nm process utilization exceeding 95% and CoWoS advanced packaging utilization approaching 98%. UMC's capacity utilization was 87.3%, with mature processes (28nm and above) exceeding 90%. SMIC's capacity utilization was 88.7%, with mature processes exceeding 90%.
In the memory chip sector, Samsung Electronics achieved DRAM capacity utilization of 92.3% and NAND Flash of 89.5%. SK Hynix achieved DRAM capacity utilization of 91.8 and NAND Flash of 88.7%. Micron Technology achieved DRAM capacity utilization of 89.2% and NAND Flash of 87.5%.
In the analog chip sector, Texas Instruments achieved capacity utilization of 86.5, while Analog Devices reached 84.3%. Both companies reported that demand growth in industrial control, automotive electronics and other sectors has driven capacity utilization improvements.
Future Trend Forecast: Structural Growth to Continue
Looking ahead to the second half of 2026, Asian semiconductor capacity utilization is expected to continue increasing, but structural differentiation will persist. Demand in areas such as AI chips, automotive electronics, and industrial control will remain strong, with related capacity utilization expected to stay above 90%. The recovery in the consumer electronics sector will be relatively slow, with limited increases in capacity utilization.
Capacity utilization for mature processes is expected to further improve, especially at nodes like 28nm and 40nm, reaching around 90%. Capacity utilization for advanced processes will remain high, but growth may slow, with manufacturers focusing more on improving capacity utilization efficiency.
As inventory levels further optimize, the semiconductor industry is expected to enter a new growth cycle. Annual Asian semiconductor capacity utilization is projected to reach around 84% in 2026, an increase of approximately 6 percentage points from 2025.
Industry Chain Impact Analysis: Capacity Structure Reshaping
The differentiation in capacity utilization is reshaping the Asian semiconductor industry landscape. The increase in mature process capacity utilization will drive demand growth for related equipment and materials, providing development opportunities for domestic semiconductor equipment manufacturers. The easing of capacity constraints in advanced processes will benefit leading players like TSMC and Samsung in expanding their market share.
For various links in the industry chain, the increase in capacity utilization will bring positive impacts: increased orders for equipment manufacturers, higher shipment volumes for material suppliers, improved capacity utilization for packaging and testing companies, and the entire industry chain is expected to enter a virtuous cycle.
However, the increase in capacity utilization also faces challenges, including talent shortages, tight equipment supply, and increasing environmental requirements. Semiconductor manufacturers need to focus on technological innovation and efficiency improvement while expanding capacity to cope with increasingly fierce market competition.
Overall, the performance of Asian semiconductor capacity utilization in Q2 2026 indicates that the industry has entered a new recovery cycle. Driven by the dual engines of AI and automotive chips, with mature processes leading the recovery, this trend is expected to continue in the coming quarters, injecting new momentum into the development of the Asian semiconductor industry.
