Infineon breaks ground on power module assembly plant in Thailand

Infineon Technologies has started construction of a new highly automated backend plant in Samut Prakan, south of Bangkok for power modules.

The first building is planned to be ready for operations at the beginning of 2026, but the company is not yet providing the expected capacity or technology level. Further ramp-up will be managed flexibly in line with market demand.

The project is supported by the Thailand Board of Investment (BOI). The highly automated fab will play a crucial role in diversifying Infineon’s manufacturing landscape as global decarbonization and climate protection efforts drive demand for power modules, e.g. in industrial applications and renewables.

“As decarbonization and digitalization are strong structural growth drivers for the semiconductor industry, we are establishing a state-of-the-art backend fab in Thailand to meet future customer demand and strengthen supply chain resilience. This investment is a key step in our strategy to further diversify our manufacturing footprint and optimize it in terms of costs, while matching the expansion of our frontend capacities,” said Rutger Wijburg, COO of Infineon. “Our new backend site is designed to operate with high efficiency, resilience and quality, ensuring that we can reliably deliver high-quality products to our customers.”

“The Thailand Board of Investment welcomes and supports the Infineon Technologies decision to invest in a new backend fab in Samut Prakan, Thailand,” said Narit Therdsteerasukdi, the BOI’s Secretary General.

“This strategic step underscores the importance of a close and reliable partnership between Infineon and the government of Thailand, and demonstrates the mutual confidence in Thailand’s business environment and growth potential. The establishment of the National Semiconductor and Advanced Electronics Policy Committee in December 2024, along with Infineon’s investment, will significantly enhance the regional semiconductor industry and ecosystem, positioning Thailand as a key player in the global semiconductor industry. We are committed to supporting the development of Thailand’s electronics industry as well as the successful implementation of the expansion of Infineon’s manufacturing site in the region.”

The plant will be part of developing a semiconductor ecosystem in Thailand, centrally located in Southeast Asia, covering key components and materials in the supply chain. A comprehensive training and education program to improve competencies in AI, digitalization and automation has been developed and the first group of Thai engineers have successfully completed this training programme at other Infineon sites. 

The new site will be equipped with solar modules, generating its own renewable energy and Infineon says it will work with local energy suppliers to ensure a reliable and green power supply.
