On July 26, 2026, the Asia-Pacific semiconductor supply chain reached a critical turning point. As global demand for AI, 5G/6G communications, and electric vehicles continues to rise, wafer foundry, IC design, and packaging/testing segments are showing divergent development trends. The three giants—TSMC, Samsung, and Intel—are in fierce competition in advanced process nodes, while mainland Chinese companies are accelerating breakthroughs in mature processes and domestic substitution. Based on the latest market data, this article outlines the investment logic of the Asia-Pacific semiconductor sector for investors.
Wafer Foundry: 3nm mass production race heats up, capacity utilization diverges
According to the latest report from industry research firm TrendForce, the global wafer foundry market grew 8.2% quarter-over-quarter in Q2 2026, with TSMC leading with a 61% market share. TSMC's 3nm (N3E) process yield has exceeded 90%, with full orders from Apple, NVIDIA, AMD and others, achieving 100% capacity utilization. Samsung Electronics follows closely; its 3nm GAA (Gate-All-Around) process has made breakthroughs in mobile AP and HPC chips, but its yield is still lower than TSMC's, causing some customers to return. Intel, through its "IDM 2.0" strategy, is accelerating external foundry business; its Intel 3 process has secured a custom chip order from Amazon AWS, but the ramp-up is slower than expected.
In contrast, mature nodes (28nm and above) face oversupply pressure. UMC, SMIC and others have seen capacity utilization drop to around 75%, with only automotive-grade chip demand remaining stable. In mainland China, SMIC's two 12-inch wafer fabs in Beijing and Shanghai have expanded smoothly, with combined monthly capacity exceeding 150,000 wafers, focusing on driver ICs, power management chips and other mature node products, but caution is needed regarding the impact of US export controls on equipment procurement.
IC Design: AI SoCs and Driver ICs Lead Growth
In IC design, AI edge computing chips have become the biggest growth driver. MediaTek released the new "Dimensity 9900" mobile platform at COMPUTEX 2026, integrating AI computing power of 35 TOPS, adopted by flagship models of OPPO, vivo and others. Realtek Semiconductor benefited from the penetration of IoT and Wi-Fi 7, with Q2 revenue up 22% YoY. In addition, driver IC giant Himax, driven by AR/VR microdisplay demand, saw its stock price rise over 15% in a single quarter.
However, US IC design companies like Qualcomm and Broadcom have lost some mainland Chinese customers due to export controls, with market share eroded by UNISOC and HiSilicon (via third-party design services). Industry insiders note that mainland Chinese IC design firms are now competitive in the mid-to-low-end market but still need to overcome dependence on EDA tools in high-performance computing, FPGA and other high-end areas.
Global Chip Trade: Geopolitics Reshapes Supply Chain
In 2026, the global chip trade landscape continues to diverge. The US CHIPS and Science Act subsidies have been distributed to the third round, with Intel, Micron, TI and others accelerating factory construction in the US, but facing labor shortages and cost overruns. Europe, through the European Chips Act, attracted Intel to build a fab in Magdeburg, Germany, but the timeline has been delayed to 2027. Japan's Rapidus, in collaboration with IBM, is driving 2nm process R&D, with trial production planned for 2027.
In the Asia-Pacific region, South Korea's Samsung and SK Hynix maintain a dominant position in the memory chip market, but HBM (high-bandwidth memory) demand is driven by AI servers, with Samsung signing a long-term supply agreement with NVIDIA. Southeast Asian countries like Malaysia and Vietnam attract foreign investment with their packaging and testing capacity advantages, but power infrastructure bottlenecks constrain expansion pace.
Cross-Market Investment Strategies: Focus on Structural Opportunities
Given the current situation, the Asia-Pacific Financial Research Institute recommends investors adopt the following strategies:
- Taiwan Semiconductor Sector: Core stocks like TSMC and MediaTek benefit from AI and 5G dividends, but valuations are high; suggest buying on dips. Key focus: TSMC (TSMC), MediaTek (MTK).
- A-share Domestic Substitution: NAURA and AMEC have made breakthroughs in etching and thin-film deposition equipment; SMIC's capacity expansion has high certainty. Risk warning: Escalation of US export controls may affect equipment procurement.
- Korean Memory Chips: HBM demand continues to boom; Samsung Electronics and SK Hynix performance may beat expectations. Note: Cycle volatility risk still needs caution.
- Southeast Asian Emerging Manufacturing: Consider Malaysian packaging and testing companies Inari and ViTrox, and Vietnamese electronics manufacturing services provider Fabrinet, benefiting from supply chain diversification trends.
Future Outlook: Three Trends Determine Industry Direction
Looking ahead to the second half of the year, the Asia-Pacific semiconductor supply chain faces three key variables: first, whether AI computing chip demand can sustain explosive growth; second, technology blockades and countermeasures resulting from US-China tech decoupling; third, the suppression of consumer electronics demand due to global macroeconomic recession risks. Overall, leading companies with technological moats and global footprints retain long-term investment value, while those relying purely on low-end manufacturing will face greater pressure.
Investors should closely monitor wafer foundry capacity utilization, IC design company inventory turnover, and semiconductor policy trends in major economies, flexibly adjusting cross-market allocation ratios.
