Chip Compass: Southeast Asia's Rise Reshapes Global Semiconductor Landscape
July 26, 2026, Shengmai Asia Pacific Comprehensive Report — The global semiconductor industry is undergoing a deep restructuring driven by both geopolitics and cost structures. Latest industry data shows that the role of Southeast Asian countries in the chip supply chain is transitioning from "passive assemblers" to "active innovators," especially in the semiconductor packaging and testing (OSAT) field, where Vietnam, Malaysia, Thailand and others saw total investment in the first half of 2026 exceed $28 billion, an annual increase of 35%, a record high.
Supply Chain Decentralization Trend Accelerates
Since the 2020s, U.S. export controls on companies like Huawei and SMIC, followed by the CHIPS and Science Act (2022) and the European Chips Act (2023), have made global semiconductor companies aware of the risks of over-concentration in Taiwan, South Korea, and Mainland China. Entering 2026, the "China Plus One" strategy has shifted from rhetoric to action. According to a Shengmai Asia Pacific survey, 8 of the world's top 10 semiconductor IDMs (Integrated Device Manufacturers) and OSAT vendors have established or expanded packaging and testing capacity in Southeast Asia. Among them, ASE's third advanced packaging plant in Penang, Malaysia, officially began production in May 2026, focusing on 3D packaging and heterogeneous integration technologies, serving AI chip giants including NVIDIA and AMD.
Vietnam: Leap from Assembly to High-End Manufacturing
Leveraging its political stability, labor cost advantages, and free trade agreements with the U.S. and EU, Vietnam has become a hotspot for this round of investment. On July 15, 2026, Intel announced an additional $2 billion investment in its chipset and test factory in Ho Chi Minh City, bringing its cumulative investment to $5 billion. Intel Vice President Kim Huat Ooi said: "Vietnam is not only a low-cost manufacturing base; its engineering talent pool is growing rapidly. We plan to upgrade the Vietnam factory into an advanced center covering system-in-package (SiP) by 2027." Additionally, in Q1 2026, Samsung Electronics launched its first overseas semiconductor packaging R&D center in Thai Nguyen Province, Vietnam, focusing on automotive chips and IoT sensors.
Malaysia: Consolidating its Position as a "Global Packaging and Testing Hub"
Malaysia has long been the largest semiconductor packaging and testing base in Southeast Asia, accounting for about 13% of the global OSAT market. However, the new wave of investment focuses on advanced processes and green manufacturing. According to data released in July 2026 by Malaysia's Ministry of International Trade and Industry (MITI), approved semiconductor-related foreign direct investment (FDI) in the first half of 2026 reached $7.8 billion, up 52% year-on-year. In addition to ASE, U.S.-based GlobalFoundries has also formed a joint venture with Malaysian partners to build a 12-inch wafer fab, expected to mass-produce 28nm and 22nm FD-SOI processes by 2028, targeting IoT and 5G RF chips. Notably, the Malaysian government passed the "National Semiconductor Strategy 2.0" in April 2026, offering tax breaks and subsidies, aiming to increase local semiconductor output to $30 billion by 2030, while requiring foreign companies to establish industry-academia cooperation centers to cultivate local talent.
Thailand: Positioning for IDM and Automotive Chips
Thailand has chosen a differentiated path, focusing on power semiconductors and automotive chips. Benefiting from the localization needs of Japanese automakers like Toyota and Honda, Thailand's Eastern Economic Corridor (EEC) has attracted investments from Infineon and ON Semiconductor. In June 2026, Infineon broke ground on a silicon carbide (SiC) wafer back-end process plant in Chonburi Province, expected to start production by the end of 2027. The plant will mainly supply the EV and renewable energy markets. BOI Secretary-General Narit Therdsteerasukdi said: "We are upgrading from an automotive assembly base to a manufacturing center for key EV components, and power chips are the core of the core."
Industry Analysis: Opportunities and Challenges Coexist
Despite Southeast Asia's booming growth, semiconductor industry leaders and analysts also point out potential challenges. First, a severe shortage of skilled talent. According to Vietnam's Ministry of Planning and Investment, the country's semiconductor industry will need about 50,000 engineers by 2030, but currently has only about 15,000. Second, infrastructure bottlenecks, including stable power supply, water resources, and logistics efficiency, with some industrial parks in Vietnam already experiencing power supply constraints. Third, geopolitical risks have not disappeared — how Southeast Asian countries maintain a balance between the U.S. and China will affect long-term investment confidence.
Shengmai Asia Pacific industry analyst Wang Mingzhe believes: "The essence of the Southeast Asian semiconductor boom is 'capability transfer' rather than 'complete substitution.' It can alleviate the vulnerability caused by over-concentration in the supply chain, but it cannot change the dominance of Taiwan and South Korea in logic chips and memory chips in the short term. However, for chip packaging and testing and mature processes, Southeast Asia will become an indispensable part in the next five years."
From the perspective of the global chip compass, the rise of Southeast Asia is not merely a simple relocation of production capacity, but an inevitable outcome of the interplay among geopolitics, technological iteration, and cost efficiency. For investors, closely monitoring policy incentives in various countries, infrastructure improvement progress, and the flow of cross-border talent will be key to seizing the next wave of semiconductor opportunities.
