Thailand accelerates bid to become regional semiconductor hub - Asia News Network

Thailand's semiconductor push is not about building fabs—it is about anchoring automotive power-device packaging and back-end assembly. The real moat is the Toyota-Honda-Isuzu OEM ecosystem, which creates genuine demand for localized SiC/GaN module packaging. But let us be blunt: Thailand lacks the ultra-pure water infrastructure, specialty gas supply chains, and cleanroom engineering talent pool required for any 12-inch wafer operation. Advanced logic is simply not on the table. The actual competitive geometry: Vietnam is bidding for consumer-electronics PTA, Thailand is positioning in automotive power semis, and Penang, Malaysia holds the legacy OSAT base. These are not zero-sum, but the decisive variable is where Washington's friend-shoring subsidies actually land. If CHIPS Act spillover funds tilt toward Southeast Asia, expect two to three power-device packaging lines in the Bangkok corridor by 2026. If subsidies stay concentrated in the US and Japan, Thailand's 'regional hub' narrative collapses into a Tier-1 supplier's annex. Twelve-to-twenty-four-month watch items: whether Infineon or onsemi commits incremental capex near the Eastern Economic Corridor, and whether Bangkok enacts a targeted tax incentive for OSAT within 2025. Without both, 'hub' remains a slide deck.
