Linde LienHwa to supply gases for Taiwanese semiconductor hub

Linde LienHwa (LLH) has signed a long-term agreement to supply ultra-high-purity gases to a state-of-the-art semiconductor advanced packaging facility in Chiayi, Taiwan. The facility, owned by one of the leading global semiconductor manufacturers, marks a key development in Taiwan’s growing role as a hub for semiconductor innovation.

Under the agreement, LLH will build, own, and operate a complex of on-site plants to supply ultra-high-purity nitrogen, oxygen, and other bulk gases critical for semiconductor manufacturing. The company has committed an investment of approximately $190 million for the project, with operations expected to commence in August 2025.

Alex Tong, President and General Manager of Linde LienHwa, expressed enthusiasm for the collaboration, stating, “We are proud and excited to have been selected as supplier to this major new facility. Our track record of safe and reliable supply over the last four decades has made Linde LienHwa the partner of choice in Taiwan. Leveraging our innovative technology and extensive experience, we continue to deliver solutions for our customers to help make them more efficient.”

Industrial gases in semiconductor manufacturing

The semiconductor industry relies on a range of industrial gases to ensure precision and quality in the manufacturing process:

• Nitrogen is used for purging and creating an inert atmosphere to prevent oxidation.
• Oxygen supports processes such as oxidation and chemical vapour deposition.
• Hydrogen is essential for heat treatment and reducing atmospheres.
• Argon ensures an inert environment during critical processes like wafer etching.
• Fluorine-based gases play a crucial role in etching and cleaning.

Taiwan’s semiconductor growth

Taiwan remains a leader in the global semiconductor market, with the industry projected to grow significantly due to rising demand for advanced chips in applications ranging from artificial intelligence to electric vehicles. 

Data from Linde LienHwa highlights Taiwan’s semiconductor market as a cornerstone of the nation’s economy, with a value exceeding $150 billion in 2023. Factors driving growth include increasing investments in advanced packaging technologies and sustained global demand.

Beyond Taiwan, Asia dominates the global semiconductor landscape, with countries like South Korea, Japan, and China playing key roles. The region accounts for over 70% of global semiconductor production.
