Western chipmakers are ramping up their presence in Southeast Asia, accelerating investments in back-end semiconductor manufacturing across ASEAN since 2023. Compared with Japanese peers, American and European integrated device manufacturers have moved more aggressively—especially in Malaysia, which is fast emerging as the region’s most sought-after destination for assembly, testing, and packaging capacity.
Japanese IDMs still maintain a strong footprint, operating a total of nine fabs across ASEAN, mainly in Malaysia, Thailand, and the Philippines. They also lead in Thailand-specific activity with two ongoing investment projects, compared with just one from their American and European counterparts in that market. This split underscores how different players are prioritizing countries within the region based on their strategic needs.
Malaysia stands out as the top choice for recent expansion by Western firms. A wave of projects from major names is either underway or planned, including:
– Intel
– Micron
– Texas Instruments (TI)
– Infineon
– Bosch
These moves reflect Malaysia’s growing role as a back-end manufacturing hub, supported by established supply chains, skilled talent, and a mature ecosystem for advanced packaging and testing.
Neighboring Singapore is also in the spotlight, with plans to deepen technological collaboration with STMicroelectronics. This strengthens the city-state’s position as a high-value node for semiconductor innovation and production within ASEAN.
What’s driving the trend? Since 2023, companies have emphasized resilience, regional diversification, and proximity to robust manufacturing ecosystems. ASEAN offers a compelling mix of infrastructure, incentives, and workforce capabilities, making it an attractive location to scale back-end operations that are critical to delivering chips at volume.
The bottom line: Western IDMs are pushing hardest on new and expanded facilities in Malaysia, while Japanese firms maintain a broader network across Malaysia, Thailand, and the Philippines with distinct investment preferences. As Singapore steps up collaboration with leading European players, the region’s role in the global semiconductor supply chain is set to grow even more prominent.
