A new chapter for Europe's semiconductor ambitions has officially begun in France.
Foxconn, Thales, and Radiall have broken ground on a joint venture named Tessalia, an advanced semiconductor packaging plant. This move is a direct response to a critical problem the tech world has faced for years: the AI chip bottleneck. For a long time, the production of high-performance chips was constrained not by the silicon itself, but by the final assembly and packaging process, which was heavily concentrated in Asia.
The causal chain leading to this moment is quite clear. First, the explosive growth in AI created an unprecedented demand for specialized chips, leading to a severe shortage in advanced packaging capacity, like TSMC’s CoWoS, starting around 2023. This highlighted the risks of a geographically concentrated supply chain.
Second, this supply crunch prompted a global push for diversification. For Europe, which aims for 'strategic autonomy,' securing its own high-end packaging capabilities became a top priority. While some facilities existed, there was a significant gap in the mass production of complex System-in-Package (SiP) modules needed for defense, aerospace, and automotive sectors—key markets for partners Thales and Radiall.
Finally, strong political will provided the necessary momentum. The EU Chips Act created a framework for subsidies and support, while the French government’s “Choose France” initiative provided the perfect platform to launch the project. This combination of market need, strategic vision, and government backing made the Tessalia venture not just possible, but logical. The plant aims to be operational by late 2029, marking a significant step toward a more resilient European tech ecosystem.
