BANGKOK — Thailand is being urged to move beyond semiconductor assembly and testing and invest more aggressively in the front end of chip production as the country seeks a bigger role in the global semiconductor supply chain.
The call comes as Thailand builds a long-term semiconductor strategy designed to attract investment, develop skilled workers and expand domestic capabilities from chip design through manufacturing.
Industry groups say the country’s existing strengths in electronics manufacturing and outsourced semiconductor assembly and testing (OSAT) provide a foundation, but greater investment in wafer fabrication and other upstream activities will be needed if Thailand wants to capture more value from the rapidly expanding chip economy.
From Assembly to the Beginning of the Chip Supply Chain
Thailand has established itself as an important electronics manufacturing base, but much of its semiconductor activity has historically been concentrated further downstream.
The country’s new strategy seeks to broaden that role.
Thailand’s Board of Investment says the government intends to encourage investment across the semiconductor value chain, including IC design, semiconductor assembly and testing, advanced electronics and wafer fabrication.
The distinction is important.
Front-end semiconductor manufacturing generally involves producing wafers and forming semiconductor devices on them, while back-end operations include processes such as packaging and testing chips after fabrication.
Moving further upstream could allow Thailand to participate in higher-value stages of production rather than relying primarily on assembly and related manufacturing activities.
Thailand Has a Long-Term Chip Investment Target
Thailand’s National Semiconductor and Advanced Electronics Strategy sets an ambitious timeline extending to 2050.
According to the BOI, the country aims to attract more than 2.5 trillion baht (about US$79 billion) in semiconductor and advanced-electronics investment over the 25-year period from 2026 to 2050.
The strategy also targets the development of more than 230,000 skilled workers and the creation of a more integrated domestic semiconductor ecosystem.
The government has described this as part of a broader effort to develop “Made-in-Thailand” chips.
Why Front-End Manufacturing Matters
The push toward wafer fabrication comes as semiconductor supply chains are being reshaped by demand for artificial intelligence, electric vehicles, renewable-energy systems, data centers and advanced electronics.
Thailand’s BOI has identified power, sensor, photonics, discrete and analog semiconductors as areas that fit the country’s existing industrial strengths.
These chip categories have applications across automotive manufacturing, energy systems, industrial equipment and data-center infrastructure.
That means Thailand does not necessarily need to replicate the most advanced logic-chip manufacturing found in Taiwan or South Korea to expand its semiconductor role.
Instead, the country’s strategy is focused on areas where its existing manufacturing ecosystem could provide a foundation for further development.
Industry Study Highlights Three Strategic Areas
A recent study presented by Thailand’s Electrical and Electronics Institute (EEI) identified three major areas for developing the country’s semiconductor industry: IC design, photonics and advanced packaging.
The study, presented in Bangkok on Sept. 8, focused on connecting Thailand’s semiconductor industry with global supply chains through international cooperation.
That approach complements the government’s broader strategy, which calls for strengthening existing capabilities while encouraging new upstream investment.
Foreign Investment Is Already Flowing Into Thailand’s Tech Sector
Thailand is not starting from zero.
The BOI reported that realized capital expenditure in high-tech manufacturing reached US$16.11 billion (530 billion baht) during the first half of 2026.
AI-related sectors, including optical transceivers, photonics, high-capacity hard disk drives and printed circuit boards, accounted for roughly half of that investment, according to the agency.
The BOI said the figures reflect rising demand for AI hardware and global efforts to diversify technology supply chains.
Thailand is now seeking to turn that investment momentum into a deeper semiconductor ecosystem.
The Race Is Regional
Thailand is competing with other Southeast Asian economies that are also seeking larger roles in semiconductor manufacturing.
Malaysia, Singapore and Vietnam have been attracting investments spanning chip fabrication, packaging, testing, equipment and design.
Thailand’s strategy therefore focuses on leveraging its existing automotive, electronics and industrial base while targeting semiconductor segments that can connect with those industries.
The government has also been courting international semiconductor companies, including upstream manufacturers, as part of its investment strategy.
The Biggest Challenge: Skills, Infrastructure and Cost
Building a semiconductor ecosystem is far more complicated than simply attracting a factory.
Wafer fabrication requires substantial capital, reliable electricity and water supplies, highly trained engineers and technicians, specialized equipment and supporting suppliers.
Thailand’s semiconductor roadmap therefore includes measures covering workforce development, technology and research, infrastructure, investment incentives and the business environment.
The government is also planning cooperation between universities, industry and research institutions to expand the specialized workforce needed for advanced semiconductor activities.
Thailand’s Semiconductor Bet Is Getting Bigger
Thailand’s push into front-end chip production represents a significant expansion of its traditional electronics role.
The country already has an established manufacturing base, but the next phase will determine whether it can build capabilities deeper in the semiconductor value chain — from chip design and photonics to advanced packaging and potentially wafer fabrication.
With AI, electric vehicles and data centers driving demand for different types of semiconductors, Thailand is positioning its industrial base for a larger role in the regional supply chain.
The challenge now is turning the country’s ambitious investment targets into actual semiconductor projects, technology capabilities and skilled workers.
