Air Liquide inaugurates its first Advanced Materials manufacturing plant in Taiwan, strengthening the next-gen semiconductor supply chain

Air Liquide unveils the successful construction of its new Advanced Materials manufacturing plant in Taichung City, Taiwan. Already present in this key innovative market with 54 facilities dedicated to the semiconductor industry in Taiwan, this is the first large-scale Air Liquide production site of advanced deposition and etching materials in Taiwan. These molecules are essential for the rise of next-generation chips powering Artificial Intelligence and High-Performance Computing. With this inauguration, Air Liquide, the world's leading supplier of gases and services to semiconductor manufacturers, accelerates its leadership in Electronics in this strategic region.

Located at the heart of the world’s most advanced semiconductor hub, the Group’s new facility will produce innovative and highly-engineered molecules designed for nano-scale processes, such as Atomic Layer Deposition (ALD). As chipmakers push semiconductors to the most extreme levels of miniaturization today approaching atomic-scale manufacturing, ensuring material reliability and performance have become strategic imperatives.

By localizing production of these tailored materials close to semiconductor manufacturers, Air Liquide provides semiconductor leaders in Taiwan and across Asia with the required quality for the next-generation of chips, while reinforcing the reliability of the supply chain. This strategic proximity fosters deeper collaboration, enabling customers to accelerate technological breakthroughs and ramp-up to high-volume manufacturing for higher yields.

This start-up completes Air Liquide’s broad ecosystem in Taiwan, where the Group has been deeply rooted for nearly 40 years. With more than 1 billion euros invested since 2019 in Taiwan, Air Liquide’s comprehensive offering now spans ultra-pure industrial gases, advanced electronic materials, distribution systems and analytical services.

Armelle Levieux, member of Air Liquide’s Executive Committee, notably supervising Electronics activities, stated: "This new plant, strategically located in Taiwan, one of the most dynamic semiconductor hubs in the world, underlines our ambition to power the next wave of technological innovation, including AI. As the industry leader in Advanced Materials for the semiconductor industry, Air Liquide is committed to strengthening its partnerships with the most advanced chipmakers in the world by providing them with state-of-the-art molecules in a context of rapid expansion. This inauguration also represents a significant milestone in our growth story in Asia, consolidating our footprint in this continent.”
