The global semiconductor industry is undergoing a quiet yet profound redistribution of power. For over a decade, memory and advanced packaging have been heavily concentrated in South Korea, while logic manufacturing has remained firmly anchored in Taiwan, China. Now, this bipolar structure is beginning to crack under the explosive demand for AI compute. The race to mass-produce HBM4E isn’t just a technical contest—it’s a stress test for whether nations can escape dependency on critical chokepoints.
South Korea’s dominance is triggering systemic risk alerts. BusinessKorea recently cited industry insiders warning that “warning lights” are flashing—Samsung Electronics and SK Hynix together control over 95% of global HBM capacity. When Nvidia shifted its Vera CPU platform entirely to LPDDR5X memory, these two Korean giants reaped nearly all the benefits. Yet such concentration becomes perilous amid escalating geopolitical tensions. The U.S. continues tightening export controls on advanced AI chips, and the stalled collaboration between Anthropic and SK Telecom exemplifies how trust fractures now permeate not just corporate partnerships but the foundational logic of international tech alliances.
Simultaneously, new forces are emerging beyond traditional manufacturing hubs. Malaysia is accelerating its positioning as a regional chip design hub. By deepening cooperation with Southeast Asian nations like Vietnam, it aims to build a secondary ecosystem encompassing IP design, localized EDA tools, and outsourced assembly and test (OSAT) services. This strategy isn’t speculative: Malaysia already hosts mature production lines from Intel, Infineon, and ASE. In 2025, its semiconductor exports grew by 18% year-over-year, with design services showing marked gains. Crucially, the country is attracting U.S. and Japanese fabless firms to establish regional R&D centers—a deliberate hedge against single-supply-chain risk.
Expanding fabrication capacity alone cannot resolve core bottlenecks. Lam Research’s CEO has bluntly stated: “New fabs by themselves won’t solve chip shortages.” Extended equipment lead times, scarcity of highly skilled engineers, and energy constraints on cleanroom operations make capacity ramp-up far more complex than headline numbers suggest. AMD’s $10 billion bet on advanced nodes in Taiwan, China bolsters its MI300 GPU competitiveness but simultaneously deepens geographic concentration. Nvidia, by contrast, pursues diversification—evaluating backend packaging options not only in Taiwan, China but also in the U.S. and Japan.
Surging AI server demand further amplifies structural contradictions. Weltrend’s fan motor driver IC order visibility now extends into 2027, reflecting the long-term nature of data center infrastructure investment. Meanwhile, the Nan Pao joint venture nearing full capacity underscores robust demand for mature-node chips in power management and sensors. This reveals an often-overlooked truth: the AI chip war isn’t fought solely on sub-7nm battlefields; it equally depends on stable supply from 28nm and above.
I judge that the next two years will be the decisive window for turning “supply chain decentralization” from rhetoric into reality. U.S. CHIPS Act subsidies, the EU Chips Act, Japan’s NEDO funding, and Southeast Asian tax incentives are collectively shaping a multipolar manufacturing network. But the real challenge lies in ecosystem coordination—building interoperable design tools, shared IP libraries, mobile talent pools, and mutual standards recognition is far harder than constructing fabs.
As Anthropic’s ASIC partnership with Microsoft potentially triggers custom chip adoption across cloud providers, supply chain resilience will hinge less on any single firm’s technological lead and more on regional clusters’ collective responsiveness. If South Korea continues relying on scale without fostering openness or deeper international collaboration, its “moat” may become an “island.” Conversely, if Southeast Asia remains confined to assembly and testing, it will struggle to enter the core tier.
The semiconductor industry stands at a crossroads: will it reinforce today’s oligopolistic structure, or cultivate a more resilient, distributed network? The answer may lie not in laboratories, but in the coordinated choices of policymakers and corporate strategists alike.
