Intel has announced plans to invest €5 billion ($5.7bn) to expand semiconductor production capacity at its Leixlip campus in Ireland.In a statement, Intel said it was increasing capacity at Fab 34 in order to manufacture its Intel Xeon processors, including Xeon 6 and next-gen Xeon built on its 3nm process node.The chipmaker plans to upgrade its existing fab by installing “leading-edge manufacturing equipment” at the facility, with infrastructure upgrades slated to include the expansion of the automated track system – an overhead conveyor belt that transports silicon wafers between different fabrication environments.“This €5bn investment represents a definitive commitment to maximize capacity at our Leixlip campus and increase what we can deliver to Intel Foundry customers," said Naga Chandrasekaran, EVP, chief technology and operations officer and GM of Intel Foundry.“By investing in our existing fabs with state-of-the-art technology and installing cutting-edge tools, we are not just increasing output of critical products like Xeon 6 and next-gen Intel Xeon processors built on Intel 3, we are ensuring that Ireland remains at the forefront of the world’s most advanced manufacturing ecosystems, while strengthening the region’s role in the global technology landscape.”Intel said that, to date, it has invested more than €30bn ($34bn) in Ireland since it began operating in the region in 1989, with the Leixlip campus serving as one of the chipmaker’s most advanced manufacturing facilities.The site employs 4,900 people; however, in 2024, it was reported that Intel was offering voluntary redundancy packages to workers in Leixlip as part of $10 billion company-wide cost-cutting efforts.In April 2026, Intel announced it had repurchased the 49 percent share that it had previously sold in Fab 34 for $14.2bn. The chipmaker purchased the equity stake from an Apollo Global Management joint venture, which acquired the stake in 2024 for $11.2bn.
