Infineon Opens New Semiconductor Manufacturing Facility in Thailand

07 October 2026 | NEWS

The Samut Prakan facility begins with more than €100 million in investment and could expand into one of Infineon’s largest backend manufacturing sites, supporting Thailand’s push into higher-value semiconductor production.

German chipmaker Infineon Technologies has opened a new semiconductor manufacturing facility in Thailand, adding backend production capacity as the country steps up efforts to secure a larger role in the global chip supply chain.

The new site in Samut Prakan, near Bangkok, begins operations with an initial investment of more than €100 million. Thailand's Board of Investment (BOI) has valued the wider multi-phase project at around US$1.4 billion, reflecting plans to expand the manufacturing complex significantly over time.

The facility initially provides around 30,000 square metres of cleanroom space and is designed to expand to as much as 150,000 square metres across five modules. Infineon said the location could eventually become one of its largest backend manufacturing operations, supporting assembly, testing and wafer-test activities for increasingly complex semiconductor products.

The investment also strengthens Infineon's manufacturing presence in Southeast Asia at a time when chipmakers are spreading production across more locations to improve supply-chain resilience. Thailand offers access to established automotive and electronics industries, regional logistics infrastructure and major Asian markets, including China.

Infineon expects the first phase of the facility to employ around 1,000 people as production ramps up. The company is also working with Thai universities, educational institutions and industry organisations to develop semiconductor skills and build a larger pool of engineers and technical workers.

For Thailand, the project forms part of a broader strategy to move beyond its established position in automotive and electronics manufacturing and develop higher-value semiconductor capabilities. The country is particularly targeting power semiconductors, including silicon carbide (SiC) and gallium nitride (GaN), as demand grows from electric vehicles, data centres, industrial automation and energy infrastructure.

Infineon's expansion could therefore play a wider role in Thailand's semiconductor ambitions by attracting suppliers, developing local technical expertise and strengthening the country's position within regional manufacturing networks. The investment also underlines Southeast Asia's growing importance as semiconductor companies diversify production and seek additional manufacturing locations close to fast-growing Asian markets.
