For example, the BOI's 18C Special Technology Regime offers up to 8 years of corporate income tax reduction for high-tech industries, attracting many international semiconductor companies to set up in Thailand. Additionally, the Thai government plans to invest tens of billions of Thai baht in building semiconductor industrial parks to further strengthen its position as a semiconductor hub in Southeast Asia.
Policy dividends not only reduce corporate investment costs but also provide a stable policy environment for investors. For investors, focusing on policy-supported areas (such as advanced packaging and testing, third-generation semiconductors) will yield higher return potential. For instance, the additional tax breaks for SiC and GaN companies by Thailand's BOI significantly increase the return on investment in these fields.
2. Accelerated Domestic Substitution: Supply Chain Restructuring and Rise of Local Enterprises
In recent years, global semiconductor supply chain restructuring has become a major trend. Geopolitical factors have increased the demand for supply chain diversification, making domestic substitution a core goal of many countries' (especially China's) semiconductor industries. Under the push for domestic substitution, local semiconductor enterprises are experiencing rapid growth opportunities.
In the storage chip sector, Chinese companies have made particularly significant progress. Changxin Memory, as a leading domestic storage chip enterprise, has entered the mainstream market with its DRAM products, breaking the monopoly of foreign companies. Moreover, Gaoyun Semiconductor's breakthrough in FPGA (Field-Programmable Gate Array) also marks the enhancement of domestic chips' competitiveness in the high-end sector. The growth of these enterprises not only promotes the domestic substitution process but also provides quality targets for investors.
In the Thai market, opportunities for domestic substitution also exist. As the supply chain migrates to Southeast Asia, Thailand, as a "semiconductor hub in Southeast Asia," has attracted the layout of many Chinese companies. For example, some Chinese packaging and testing companies have set up production bases in Thailand, leveraging Thailand's policy advantages and labor cost advantages to expand into the international market. For investors, focusing on domestic semiconductor enterprises布局 in Thailand will yield the dividends from supply chain restructuring.
3. Demand Explosion: Dual Engines of AI Computing Power and Automotive Chips
Demand is the core driver of growth in the semiconductor industry. In 2026, AI computing power demand and automotive chip demand have become the two major growth engines.
In terms of AI computing power demand, the popularity of generative AI has led to a surge in demand for high-performance chips in AI servers. The architecture of AI inference chips is undergoing a "shake-up," with ASIC (Application-Specific Integrated Circuit) gradually eroding GPU's market share due to its high energy efficiency. For example, specialized chips like Google's TPU and Nvidia's DPU are increasingly used in AI inference. Additionally, HBM (High Bandwidth Memory), as a core component of AI servers, has seen a significant increase in demand, leading to a shortage in the DRAM market. According to data from the World Semiconductor Trade Statistics (WSTS), global DRAM sales are expected to grow by 15% year-on-year in 2026, with AI server demand contributing the most to this growth.
In terms of automotive chip demand, the popularization of electric vehicles and autonomous driving has driven the expansion of the automotive chip market. Electric vehicles require a large number of power semiconductors (such as SiC, GaN) to improve energy efficiency, while autonomous driving requires high-performance sensor chips and processor chips. According to industry data, the global automotive chip market size is expected to reach $150 billion in 2026, with a growth rate exceeding 20%. As a major automobile manufacturing country, Thailand has particularly strong demand for automotive chips. For example, the demand from Thai automobile manufacturers for power semiconductors and autonomous driving chips continues to grow, providing a broad market space for semiconductor companies.
4. Technological Breakthroughs: New Opportunities in Advanced Packaging and Third-Generation Semiconductors
Technological breakthroughs are the core driver of development in the semiconductor industry. In 2026, advanced packaging and third-generation semiconductors have become the focus of investors.
In terms of advanced packaging, as chip integration increases, advanced packaging technologies (such as 2.5D/3D packaging, Chiplet) have become key to solving performance bottlenecks. Leading enterprises like TSMC and Samsung have launched advanced packaging solutions, and Thailand's packaging and testing chain is also actively deploying. For example, Thailand's packaging and testing capacity utilization rate exceeded 90% in Q3 2026, showing strong demand for advanced packaging. For investors, focusing on enterprises布局 in advanced packaging in Thailand will yield the dividends from technological upgrades.
In terms of third-generation semiconductors, SiC (silicon carbide) and GaN (gallium nitride) have become important development directions in the power semiconductor field due to their high energy efficiency and high voltage resistance. In recent years, the domestication process of third-generation semiconductors has accelerated. For example, breakthroughs in domestic gallium nitride substrates have reduced production costs. The Thai government has also listed third-generation semiconductors as a key development area, attracting enterprises to set up through policy support. For example, the super incentive package of Thailand's BOI provides additional tax breaks for SiC and GaN companies. For investors, third-generation semiconductors are a golden track for the next decade and deserve attention.
5. Unique Advantages of Thailand's Market: Layout of the Investment Hotspot
As a semiconductor investment hotspot in Southeast Asia, Thailand has unique advantages. First, Thailand has a complete semiconductor industry chain, including wafer manufacturing, packaging and testing, and materials. Second, Thailand has relatively low labor costs and a certain technical talent pool. Additionally, the policy support provided by the Thai government (such as BOI incentives) has attracted many international enterprises to set up.
According to industry data, Thailand's semiconductor export value is expected to grow by 20% year-on-year in 2026, with advanced packaging and testing and third-generation semiconductors contributing the most.
