Infineon Technologies has opened a new backend manufacturing facility near Bangkok, investing more than €100 million in a site the German chipmaker designed for staged expansion. The plant starts with up to 30,000 sq m of cleanroom space and can grow to 150,000 sq m as demand increases.

The facility will process, assemble and test chips before they reach customers. Backend manufacturing, where devices are assembled and tested, is a critical late-stage step in chip production. Infineon Chief Operations Officer Alexander Gorskitold described the investment as strategic, citing Thailand's proximity to major markets including China.

The site adds a fourteenth candidate to Infineon's manufacturing footprint — the company already operates 13 sites across the US, Europe, China and Southeast Asia. Infineon plans to use the Thailand facility as an additional sourcing option for customers, allowing production to shift between locations when disruptions affect another site. For manufacturers, spreading production across multiple locations reduces supply-chain concentration and provides flexibility when individual plants face operational problems.

Thailand Targets $18 Billion by 2030

The investment lands as Thailand accelerates its push to become a semiconductor and advanced electronics hub. The government is targeting $18 billion in semiconductor investments by 2030, with a focus on photonics, power electronics and sensors. Bangkok is backing the effort with financial incentives and workforce development programs.

Thailand Board of Investment Secretary General Narit Therdsteerasukdi said the country attracted around 910 billion baht ($27.12 billion) in semiconductor and advanced electronics investments between 2023 and July 2026.

Talent development is a parallel priority. Thailand aims to train nearly 85,000 skilled workers and more than 1,700 researchers by 2030, on the premise that workforce capability will determine whether semiconductor investments stick.

Demand Context

The expansion arrives during a new period of rapid growth in chip demand. Industry forecasts put global semiconductor sales at $1 trillion in 2026, with potential to double to $2 trillion by 2035, driven significantly by data center buildout for artificial intelligence workloads.

That demand curve is pushing semiconductor companies to diversify manufacturing networks across Asia. Infineon's Bangkok plant, with its fivefold cleanroom expansion headroom, gives the company capacity to scale without securing a new site.

For Thailand, the project is more than a single corporate investment. If global chip demand continues to expand as forecast, facilities like this one will shape Southeast Asia's evolving position in the semiconductor supply chain — and Bangkok has staked $18 billion on that outcome.
