Bangkok – October 01, 2026 -- Infineon Technologies AG has officially opened a new backend semiconductor manufacturing site in Samut Prakan, Bangkok, designed to scale up to five production modules and employ up to 1,000 workers as it ramps.
Infineon inaugurates greenfield site with Thai Prime Minister in attendance
The facility was inaugurated jointly by Anutin Charnvirakul, Prime Minister of Thailand, and Alexander Gorski, Chief Operations Officer of Infineon Technologies. The company frames the site as a strategic diversification move for its global manufacturing network, complementing ongoing frontend capacity expansion elsewhere.
Workforce set to nearly triple from 350 to 1,000 as Module A ramps
The site currently employs around 350 people. Infineon expects that number to grow to approximately 1,000 as its first building, Module A, reaches full production capacity. The company said it is supporting talent development through partnerships with universities and industry players in Thailand.
Facility built for phased expansion across five modules
Gorski said the Bangkok location combines access to Southeast Asian logistics networks with long-term scalability. "We have built the Bangkok site with the future in mind," he said, noting the site can grow from its initial module to up to five over time, positioning it to become one of Infineon's largest backend manufacturing hubs.
Site covers full backend process spectrum including wafer test
The plant is equipped with cleanroom, assembly and test capabilities alongside wafer test functions, supported by high automation levels and a digital manufacturing backbone. Infineon said the combination enables production of increasingly complex, high-value semiconductor solutions for automotive, industrial and energy infrastructure applications tied to electrification and digitalization.
Plant runs entirely on green electricity with on-site solar and water recycling
Infineon said the Bangkok facility operates on 100 percent green electricity and incorporates water recycling, rainwater collection and on-site solar modules generating renewable energy, measures it ties to reducing carbon footprint across its value chain.
Thai government frames investment as semiconductor ecosystem milestone
Charnvirakul called the investment "a strong vote of confidence in Thailand's future as a leading semiconductor location," citing the country's national technology strategy and existing semiconductor manufacturing heritage as factors drawing the investment.
