Chip wars escalate: U.S. races for 20% market share as southeast asia rises and supply chains split

By early 2026, the bipartisan support for the CHIPS Act had solidified a robust policy foundation enabling significant expansion of domestic semiconductor manufacturing, exemplified by TSMC's production of leading-edge chips in Arizona mirroring their Taipei operations. This legislative continuity has been pivotal in the U.S. aiming to capture 20% of global leading-edge chip production by 2030, a strategic pivot from zero domestic capacity just a few years prior. However, as Commerce Secretary Gina Raimondo acknowledged, full self-sufficiency remains unattainable due to constraints in workforce, land, and energy, making strategic collaboration with allies essential to bolster supply chain resilience and reduce overreliance on China.

Despite progress in chip fabrication, advanced semiconductor packaging remains a critical bottleneck, with U.S.-made chips still shipped abroad—primarily to Taiwan—for sophisticated packaging processes. This dependency underscores ongoing vulnerabilities in the supply chain, compounded by the fact that approximately 30% of printed circuit boards and nearly all chemical and substrate inputs are imported from China or Asia. These realities highlight the urgent need for domestic capability expansion and diversification of supply sources to mitigate geopolitical risks.

The CHIPS Act laid the groundwork for supply chain diversification well before recent tariff escalations, which have since accelerated efforts to localize semiconductor production. This bipartisan momentum is fueling massive capital investments not only in the U.S. but also in allied regions such as Vietnam, Malaysia, Mexico, and Europe, aiming to create a more resilient and secure semiconductor ecosystem. This strategic bifurcation addresses geopolitical and security concerns by balancing cost efficiencies with the imperative to reduce dependence on the China-Taiwan axis.

By early 2026, global trade group SEMI, representing industry giants like Intel and AMD, underscored the urgent need for Southeast Asia to expand its semiconductor fabrication capacity to diversify the supply chain and reduce geopolitical risks. Despite Asia's ambitious plan to add 64 new fabs by 2029, only six are slated for Southeast Asia, with the majority concentrated in China and Taiwan, exposing the industry to vulnerabilities highlighted by recent disruptions such as the COVID-19 pandemic and escalating U.S.-China trade tensions.

Amid rising tariffs and geopolitical uncertainties, Southeast Asian countries like Malaysia and Vietnam are increasingly emerging as attractive alternatives to traditional semiconductor hubs such as Taiwan and South Korea. This shift reflects a strategic realignment as companies seek to mitigate risks by spreading design and manufacturing across multiple countries, creating a more complex but resilient supply chain that leverages Southeast Asia’s growing production capabilities.

By mid-2026, advanced packaging technologies such as chiplet-based designs and 3D integration have become pivotal drivers of growth in the semiconductor bonding market, projected to expand from USD 1.19 billion in 2026 to USD 1.45 billion by 2031. This surge is underpinned by government initiatives exceeding USD 80 billion worldwide, which are accelerating capacity expansions to meet the soaring demand fueled by AI and edge computing applications, thereby enhancing both performance and supply chain resilience.

The semiconductor packaging ecosystem is undergoing a pronounced bifurcation, with Asia-Pacific—particularly Taiwan and South Korea—dominating advanced heterogeneous integration through foundries and leading OSAT companies, while China commands the conventional assembly and module integration segments. This division not only reflects differing technological focuses but also introduces overlapping supply chains characterized by distinct standards, cost structures, and geopolitical risks, effectively creating a semi-independent Chinese ecosystem alongside a U.S.-led advanced technology frontier.

The rising complexity of semiconductor devices, especially those integrating AI and high-bandwidth memory (HBM), has elevated the strategic importance of packaging and testing technologies, with SEMI forecasting test equipment sales to climb 31% to $15.3 billion in 2026 and assembly and packaging equipment sales to grow 9.6% to $6.7 billion. This trend underscores the critical role of die-to-die bonding—which currently accounts for 53.91% of interconnect-related revenue—in enabling heterogeneous integration and meeting the performance demands of next-generation semiconductor solutions.

By mid-2026, the semiconductor market is poised for robust growth, with projections estimating an increase from USD 0.74 trillion in 2026 to USD 1.01 trillion by 2031, fueled primarily by surging demand in AI infrastructure and electric vehicles. Integrated circuits dominate this expansion, commanding a 78.33% market share driven by AI processors, high-bandwidth memory, and automotive electronics. Concurrently, the semiconductor bonding market is set to grow from USD 1.19 billion to USD 1.45 billion over the same period, propelled by advanced packaging technologies such as chiplet-based designs and 3D integration, with die-to-die bonding capturing over half of interconnect-related revenues as the industry shifts toward heterogeneous integration for enhanced performance and efficiency.

Government initiatives exceeding USD 80 billion across major economies are catalyzing capacity expansions and accelerating demand for next-generation bonding solutions, particularly those enabling AI and edge computing applications. This substantial public investment is complemented by strategic infrastructure developments in North America and the Middle East, which are emerging as significant players alongside the Asia-Pacific region, the longstanding manufacturing hub benefiting from strong investments and an established ecosystem. These efforts collectively reflect the industry's response to lithography bottlenecks and geopolitical tensions by fostering diversified and resilient supply chains.

Reflecting a broader global trend toward supply chain diversification and localization, significant reshoring efforts are underway in North America, especially in semiconductor and medical device manufacturing. As Sono-Tek CEO Steve Harshbarger observed, while North America is ramping up domestic investments, Asia and Europe will remain critical regions due to their concentration of advanced manufacturing activities, underscoring a multi-regional approach to balancing growth, innovation, and geopolitical risk in the semiconductor sector.
