1. Market Overview: Boom Climbs Broadly
On July 26, 2026, the global semiconductor market continues the strong recovery momentum since Q2. According to TrendForce latest data, Q3 global chip foundry capacity utilization has climbed above 92%, a near two-year high. Among them, advanced process nodes are particularly hot: TSMC's 3nm (N3E) process capacity utilization reached 100% in July, with order backlog extending to Q1 2027. Driven by this, semiconductor equipment, materials, and packaging/testing segments all face supply shortage, and stock prices of upstream and downstream companies rose together. As of today's close, the Philadelphia Semiconductor Index (SOX) rose 2.3% to 5,840 points, with year-to-date gains of 35%.
2. Leader Leads: TSMC 3nm Capacity Full
As the global foundry leader, TSMC's advanced process capacity utilization is often seen as the "barometer" of the semiconductor industry. On July 26, TSMC revealed at its earnings call that since mass production in H2 2025, 3nm yield has exceeded 90%, and customer demand continues to exceed expectations. Besides traditional major customers like Apple, Nvidia, and AMD, mobile chip makers Qualcomm and MediaTek are also accelerating adoption of 3nm technology. Currently, TSMC's monthly 3nm capacity has expanded to 120,000 wafers but still falls short of demand. The company plans to increase 3nm capacity to 150,000 wafers per month by 2027. Affected by this news, TSMC's US stock (TSM) closed up 3.5% at $172.8 today.
The full-capacity effect at TSMC has transmitted to upstream equipment. Global lithography leader ASML announced today that EUV (extreme ultraviolet lithography) shipments reached 18 units in Q2 2026, a single-quarter record, with the vast majority supplied to TSMC for 3nm expansion. ASML also raised its full-year revenue guidance to €30 billion, up 25% year-on-year. Tokyo Electron also saw its stock rise 4.2% today due to surging orders for etching and deposition equipment.
3. Supply-Demand: Structural Shortage and Inventory Restocking Coexist
On the demand side, AI chips, high-performance computing (HPC), smartphone SoCs, and automotive electronics are the main drivers of this recovery. Nvidia's latest Blackwell Ultra GPU sees strong demand, tightening 2.5D advanced packaging capacity. TSMC's CoWoS packaging capacity utilization also exceeded 98% in July. Meanwhile, in memory chips, HBM (high-bandwidth memory) orders are full, with Samsung and SK Hynix accelerating expansion. DRAM mainstream DDR5 prices rose 8% month-on-month in July, and NAND Flash prices also rose.
However, the global semiconductor market is not overheated across the board. Mature process (28nm and above) capacity utilization remains only around 85%, and consumer electronics chips (e.g., MCU, power management IC) are still in a moderate recovery. Analysts at Taiwan's Institute for Economic Research point out that this recovery shows a K-shaped divergence with "advanced process leading, mature process following." Overall, global chip inventory has fallen from high levels at end-2025 to healthy levels, and the industry has entered an active inventory restocking cycle.
4. Regional Dynamics: US CHIPS Act Accelerates, Southeast Asia Capacity Builds Up
Under the US CHIPS and Science Act framework, TSMC's Arizona fab has entered trial production, with mass production possibly moved up to Q1 2027. Intel's Ohio wafer fab also received $1.5 billion in direct subsidies from the US Department of Commerce this week for advanced process R&D. Meanwhile, the Southeast Asia semiconductor ecosystem is expanding significantly: packaging and testing capacity in Penang, Malaysia, and Ayutthaya, Thailand, continues to grow. ASE Technology announced on July 26 an investment of THB 20 billion to establish an advanced packaging base in Thailand, expected to start production in 2028. Samsung Electronics in Vietnam also announced expansion of its back-end packaging and testing plant in Bac Ninh Province to meet global customers' supply chain diversification needs.
China's domestic semiconductor industry is also catching up fast. SMIC announced today that its N+2 process (equivalent to 7nm) yield has exceeded 85%, monthly capacity increased to 50,000 wafers, and it has received first orders from domestic AI chip design companies. Additionally, Yangtze Memory Technologies' 232-layer 3D NAND Flash single-chip capacity has exceeded 2Tb, and the industry believes China's memory industry is rapidly narrowing the gap with Korean and US giants. However, the US Department of Commerce on July 25 expanded export controls on advanced chip-making equipment to China, adding restrictions on sub-14nm process equipment, which may disrupt China's semiconductor development in the short term.
5. Investment Analysis: Focus on Advanced Process and Innovative Materials
The recent strength in semiconductor stocks has fundamental support. Morgan Stanley's latest report states that the global semiconductor industry is at the start of a "super cycle," benefiting from rising penetration of AI, autonomous driving, and IoT technologies. The firm raised its 2026 global semiconductor sales growth forecast from 12% to 17%, expecting the market to surpass $700 billion. Investment directions: focus on three main themes:
- Advanced process foundry and IP: TSMC, Samsung Electronics, and IP licensing leader ARM Holdings;
- Key equipment and materials: ASML, Applied Materials, Shin-Etsu Chemical, Showa Denko;
- Emerging application chip design: Nvidia, AMD, Broadcom, and domestic RISC-V ecosystem companies.
Risks: investors should watch for escalation of US-China tech rivalry, weaker-than-expected recovery in electronic terminal demand, and oversupply risk from excessive chip capacity expansion.
6. Conclusion
Overall, the semiconductor market in July 2026 shows three features: "strong leader, hot advanced process, solid recovery." TSMC's full 3nm capacity is the strongest signal of this cycle, benefiting the entire industry chain. For investors, it's a good time to position in sub-sector leaders with technological moats at reasonable valuations. As the traditional peak season of Q3 arrives, the semiconductor sector is likely to continue its upward trend.
