This development aligns with BASF’s ongoing commitment to creating supply chain 
resilience for the European semiconductor sector, crucial for maintaining 
technological competitiveness in a rapidly evolving market. Operations are 
expected to start in 2027. 


With several new chip manufacturing plants being constructed or expanded in 
Europe, there is an increasingly strong demand for high-quality and high-purity 
semiconductor-grade chemicals, such as ammonium hydroxide. This need has 
been accelerated by a close cooperation partner of BASF, who is currently building 
a new chip production plant in Europe. BASF is investing in the semiconductor chemical value chain based on mutual long-term customer-supplier commitments 
with its strategic partners.


NH4OH EG produced at the new plant will be essential for advanced nodes chip 
technology, enabling the next generation of semiconductors that are vital for key 
European industries, including Automotive, AI and beyond.


“We are thankful and proud of our customers’ trust in BASF to be a long-term 
strategic partner in their growth ambition in the region.” said Jens Liebermann, 
Senior Vice President, Electronic Materials at BASF. “This new investment not only 
further enhances our capabilities but also reinforces our commitment and our 
presence to supporting the semiconductor industry in Europe.” said Gops Pillay, 
President, Global Operating Division, BASF.


BASF is dedicated to fostering innovation and sustainability, and this new plant will 
play a pivotal role in driving forward both for the semiconductor industry while 
contributing to the European economy.


BASF is a global leader in supplying the semiconductor industry with high-purity 
single bulk chemicals and specialized chemical formulations essential for 
semiconductor manufacturing. The company offers a comprehensive portfolio of 
materials primarily used in semiconductor production processes, including cleaning, 
etching, photo, metal deposition, and chemical mechanical planarization.
