Infineon Technologies has inaugurated a US$1.4 billion (48 billion baht) power semiconductor manufacturing complex in Samut Prakan province, Thailand's largest foreign chip investment to date and the anchor of Bangkok's newly approved National Semiconductor and Advanced Electronics Strategy.

Prime Minister Anutin Charnvirakul opened the facility on Thursday, October 1, and used the occasion to lay out a roadmap that runs to 2050 under the "Made-in-Thailand Chip" initiative. The strategy targets power semiconductors, sensors and photonics as priority segments, supported by five pillars: investment, talent, technology, infrastructure and the business environment.

"The semiconductor ecosystem is deeply interconnected, and Thailand is stepping up to play an increasingly important role in the global supply chain," Anutin said. "Thailand's National Semiconductor Strategy sets a clear direction for building a competitive and resilient chip industry."

What does the Samut Prakan complex produce?

The Infineon site is planned across five modules and, when fully developed, is expected to become the German company's largest back-end assembly and testing centre worldwide. The BOI-promoted project is expected to create more than 5,000 skilled local jobs.

Power semiconductors made at such facilities feed directly into the demand cycles the Thai government is chasing: AI data centres, electric vehicles, clean energy systems and industrial automation.

Deputy Prime Minister and Finance Minister Ekniti Nitithanprapas tied the investment to Thailand's twin-track digital agenda.

"Thailand must advance on two fronts simultaneously: 'AI in All', applying AI to raise productivity across every sector of the economy, and 'All in AI', building the infrastructure and ecosystem that the AI economy requires," Ekniti said.

How does Thailand plan to move beyond assembly?

The government's stated ambition goes well beyond attracting factories. Narit Therdsteerasukdi, secretary-general of the Thailand Board of Investment, framed the strategy as a capability-building exercise.

"Our strategy goes far beyond attracting capital or adding production capacity; it is about building technological capability in Thailand," Narit said. "Attracting the world's leading power semiconductor company demonstrates Thailand's readiness to supply critical components for global trends such as digitalisation and the energy transition, and advances our long-term vision of chips engineered and made in Thailand."

The talent pipeline is concrete. Infineon is working with the Thai Semiconductor Industry Association and local universities to:

• develop at least 60 specialised semiconductor courses;
• train 1,100 undergraduate students;
• support 18 joint research and development projects.

Anutin praised the company for recruiting and training Thai engineers, including through international training opportunities. "Building a semiconductor industry is not only about facilities; it is about people," he said.

Can FastPass shorten investment timelines?

To accelerate projects of this kind, the government is deploying the Thailand FastPass framework, which coordinates the agencies responsible for energy, customs, industrial estates and environmental approvals. The stated aim is to compress the time between an investment decision and implementation.

For a back-end assembly and test operation — where speed to capacity matters more than leading-edge process technology — permitting velocity is a genuine competitive lever against regional rivals for the same foreign direct investment.

Ekniti said the goal is to convert investments of this scale into technology transfer, high-skilled jobs and stronger local supply chains. Anutin went further, encouraging Infineon to explore higher-value and upstream activities in Thailand as the country seeks a deeper position in global semiconductor supply chains.

"Together, we can build a semiconductor supply chain that is competitive, resilient, secure, and sustainable, and make Thailand an increasingly important part of Infineon's global success," Anutin concluded.

With a $1.4 billion complex now operating, 5,000 jobs in prospect and a 2050 roadmap in force, Thailand's credibility as a regional chip hub will next be tested by whether FastPass and the talent programmes can attract a second wave of investment beyond back-end.
