Intel boosts Leixlip chip plant with EUR €5 billion

Intel has announced a €5 billion expansion at its Leixlip campus in Ireland, increasing manufacturing output at one of its main European semiconductor sites.

The project marks the next stage of capacity growth at the campus, focusing on upgrades to existing fabrication facilities. It also includes new manufacturing equipment and infrastructure changes across the site.

Work began earlier this year as part of a capital expenditure programme to raise output from the Irish operation. The expansion will use existing cleanroom space at Leixlip while supporting more research and development activity.

The site will produce Intel Xeon 6 and next-generation Intel Xeon processors built on Intel 3 process technology. Those chips target markets where demand for advanced silicon has risen sharply.

Site upgrades

A central part of the programme is the expansion of the campus automated track system, which will connect separate modules across the site into a single high-velocity production environment.

The investment is also expected to create work for specialised tradespeople involved in construction and equipment installation, alongside full-time roles at the campus. Intel has operated Leixlip since 1989 and employs 4,900 people there.

Leixlip is one of Intel's most advanced manufacturing facilities and has been a significant part of its European footprint for decades. Intel has invested more than €30 billion in Ireland since establishing operations there.

The announcement comes as governments and chipmakers in Europe seek to increase regional semiconductor production and reduce dependence on overseas supply. The new spending is intended to strengthen Europe's semiconductor supply chain and support a more resilient domestic source of processors.

Naga Chandrasekaran, Executive Vice President, Chief Technology and Operations Officer, and General Manager of Intel Foundry, said the expansion reflected Intel's commitment to increasing capacity at Leixlip.

"This €5 billion investment represents a definitive commitment to maximize capacity at our Leixlip campus and increase what we can deliver to Intel Foundry customers. 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," he said.

National focus

The expansion also carries weight for Ireland's industrial policy, where semiconductor manufacturing has long been a priority. The country has sought to position itself as a European centre for advanced manufacturing, supported by multinational investment and a large technical workforce.

Micheál Martin linked the Intel decision to Ireland's wider economic strategy.

"Intel's latest multi-billion-euro investment in Leixlip is a powerful vote of confidence in Ireland, our skills base and our position at the heart of Europe's most advanced manufacturing ecosystem. At a time of rapid technological change and global competition, this expansion strengthens Ireland's role in securing resilient semiconductor supply chains and reinforces our ambition to remain a global leader in innovation, productivity and sustainable economic growth," he said.

IDA Ireland, which works to attract foreign direct investment, described Intel as one of the state's most significant long-term investors. The agency said the project highlighted the role of Ireland's workforce and innovation base in attracting new semiconductor manufacturing activity.

"Intel is one of Ireland's longest standing and most strategically important investors. This project demonstrates the value of Ireland's skilled workforce, innovation ecosystem and stable business environment, while reinforcing Ireland's leadership in advanced semiconductor manufacturing, supporting both European competitiveness and resilient global supply chains," said Lohan.
