1. AI Memory Chip Demand Surges, Samsung and SK Hynix Q2 Results Beat Expectations
On July 28, 2026, global memory chip leaders Samsung Electronics and SK Hynix released their Q2 2026 financial results. Data showed both companies significantly exceeded market expectations in revenue and net profit, driven by strong AI server demand for high-bandwidth memory (HBM) and enterprise SSDs. Samsung's semiconductor division posted 38% year-over-year revenue growth in Q2, with HBM3E shipments up over 50% sequentially. SK Hynix recorded 45% revenue growth year-over-year, with net profit hitting a record high. This signals AI chip demand expanding from training to inference, continuously driving memory chip volume and price increases.
Boosted by this, the Asian semiconductor sector rallied on July 29, with Samsung shares rising 4.2% intraday and SK Hynix up 5.6%. Analysts note that HBM, as a core bottleneck for AI computing, will remain in short supply through H2 2026, with the full-year HBM market value expected to exceed $30 billion, making it the most lucrative segment in the semiconductor market.
2. TSMC Doubles CoWoS Capacity, Advanced Packaging Becomes New Battleground
Meanwhile, foundry leader TSMC announced a new round of advanced packaging capacity expansion, planning to more than double its monthly CoWoS (Chip-on-Wafer-on-Substrate) capacity by 2027. TSMC stated that AI chip customers' demand for 2.5D/3D packaging far exceeds expectations, with existing fabs in Longtan, Hsinchu, and Tainan fully utilized. The company will add new packaging lines in Central Taiwan and overseas (including potential sites in Vietnam or Japan). This move directly drives demand for semiconductor equipment and materials, especially for packaging equipment makers like ASMPT and Tokyo Electron, which saw order surges.
Advanced packaging is no longer just a back-end process but a key lever for improving chip performance and integration. For example, NVIDIA's Blackwell architecture GPUs heavily use CoWoS-L technology, while AMD's MI400 adopts a similar approach. As major chip design companies accelerate adoption of chiplet architectures, the scarcity of advanced packaging capacity will persist long-term, becoming a core variable affecting global semiconductor supply-demand balance.
3. From Imbalance to Structural Growth: Semiconductor Market Enters New Cycle
The AI arms race since 2025 has changed traditional semiconductor cycle patterns. The consumer electronics-driven "shortage-surplus-rebalancing" model is being replaced by AI infrastructure investment-driven structural growth. Data shows global semiconductor sales in Q2 2026 grew 12.3% year-over-year, but memory chip growth hit 28% versus logic's 6%. More critically, chip inventory days fell from mid-year highs to reasonable levels, indicating downstream destocking near completion and restocking demand emerging.
From wafer pricing, advanced node (7nm and below) capacity utilization remains above 95%, with foundry prices firm; while mature nodes (28nm and above) saw slight price softening due to weak consumer electronics demand. This divergence is expected to continue into 2027. For investors, focusing on AI-related chips, advanced packaging, and HBM supply chains remains the core strategy for excess returns.
4. Vietnam Packaging & Testing Chain Faces Strategic Opportunity, Localization Accelerates
Against the backdrop of global supply chain restructuring, Vietnam is emerging as a potential destination for advanced packaging capacity spillover. Intel's packaging and testing base in Ho Chi Minh City already has an annual output value exceeding $15 billion and is expanding CoWoS-related lines; Samsung Electronics is expanding its memory packaging and testing factory in Bac Ninh Province. Vietnam's recently released "Semiconductor Development Strategy" explicitly aims to build 10+ advanced packaging and testing plants by 2030, offering corporate income tax incentives such as "four exemptions and nine reductions by half." For semiconductor companies setting up in Vietnam, localizing packaging and testing not only reduces costs but also mitigates geopolitical risks, aligning with the "China+1" industry trend.
Meanwhile, Vietnam's local IC design firms and packaging startups are rising, such as VinaIC's advanced packaging subsidiary, which secured Series A funding from a Singapore sovereign fund. Over the next two to three years, Vietnam is expected to become one of the fastest-growing regions globally for advanced packaging capacity, injecting new momentum into the semiconductor market.
5. Outlook: Focus on H2 Supply-Demand Rhythm and Geopolitical Variables
Looking ahead to H2 2026, the semiconductor market faces multiple intertwined factors: sustained AI chip order volume, consumer electronics peak season (e.g., new iPhones, Android flagships) potentially boosting mature nodes, and US export control policy impacts on domestic fab expansions. Overall, structural strength in memory and advanced packaging remains highly certain.
Investors should focus on: HBM supply chain (precursors, TSV equipment, test equipment), CoWoS-related equipment and material suppliers, and Vietnam packaging & testing concept stocks. Also, closely watch TSMC's overseas packaging fab site selection, which will be the next catalyst.
In summary, the July 2026 semiconductor market has moved from "AI story" to "earnings realization." The rapid expansion of advanced packaging capacity is both demand-driven and a mark of industry upgrading. With AI infrastructure investment growing 25%-30% annually, the semiconductor industry is entering a new growth cycle, and Vietnam, as a key Southeast Asian semiconductor supply chain node, warrants long-term attention for its investment value.
