**Introduction** The Association of Southeast Asian Nations (ASEAN)’s semiconductor growth — especially in assembly, testing, and packaging — benefits from diversification of production networks and expanding electronics manufacturing capacity. Long-term competitiveness could be undermined by structural lock-in in lower value-added segments, dependence on external technology chokepoints, rising compliance and policy risk in a more fragmented trade environment, infrastructure and utility reliability constraints, and persistent gaps in skills and innovation depth[1][2][3][4][5]. **Risks to ASEAN semiconductor growth and long-term competitiveness** **1.** **Limited participation in fabrication and design activities** value chains are highly segmented, and the highest value-added activities — including leading-edge fabrication, semiconductor manufacturing equipment, and core design capabilities — remain concentrated outside most ASEAN economies[1][2]. If upgrading into advanced packaging capabilities, chip design and process engineering functions, and upstream materials and supplier development does not deepen, ASEAN risks continued exposure to margin compression and the relocation of lower value-added backend operations[1][5]. **2.** **Dependence on technology chokepoints outside the region** Semiconductor production depends on critical upstream inputs with limited substitutability, including advanced manufacturing equipment, electronic design automation software, and specialized materials. These chokepoints are highly concentrated, creating exposure to licensing constraints, supply disruptions, and policy-driven restrictions that can delay capacity expansion and limit movement into higher value-added semiconductor activities[1][2]. **3.** **Geoeconomic fragmentation and rising compliance burdens** Semiconductor production is increasingly affected by export controls, investment screening, and other security-related trade measures that raise uncertainty and compliance costs across production networks[2][3]. The continued expansion of such measures increases the risk of abrupt changes to market access, input availability, and investment conditions[3]. These dynamics can redirect investment toward jurisdictions with clearer access to advanced technology and more stable regulatory alignment, reducing ASEAN’s ability to attract long-term investment in fabrication and other higher value-added semiconductor activities[2][3]. **4.** **Power, water, and infrastructure reliability** Semiconductor fabrication and advanced packaging require highly reliable electricity, stable transport networks, substantial water supply, and advanced cleanroom infrastructure. Disruptions in power supply, logistics, or water availability translate directly into yield loss, production downtime, and higher operating costs[2][4]. Slower global investment growth increases the importance of infrastructure stability in decisions on plant location and expansion[4]. **5.** **Workforce shortages and limited research capacity** Semiconductor fabrication and advanced packaging require sustained availability of specialized technical personnel and applied research capability. Where training pipelines are limited, expansion can lead to hiring bottlenecks, higher labor costs, increased turnover, and delays in bringing new production lines online[1][2]. At the same time, the wider use of local content and related industrial policy requirements in other jurisdictions can influence sourcing decisions and increase compliance costs[5]. For production bases with limited domestic supplier capability in specialized inputs and services, these pressures can constrain expansion into more advanced semiconductor activities. **Conclusion** ASEAN’s semiconductor growth remains exposed to structural and policy risks: continued concentration in assembly, testing, and packaging; dependence on external suppliers of advanced equipment and design tools; expanding security-related trade measures; infrastructure and utility reliability constraints; and workforce and research limitations. Long-term competitiveness depends on whether current expansion results in greater participation in fabrication, advanced packaging, semiconductor design, and specialized supplier activities, rather than remaining concentrated in lower value-added production stages.
