About Us

Established in Ireland by Mr. Paul Cahill, CSI Semiconductor Solutions grew out of a firsthand understanding of academic and industrial research needs. Transitioning from advanced material science research and engineering lecturing into full scale semiconductor supply, Paul established CSI Semi in 2014 to bridge a vital gap in the market: providing dependable, high-quality pre-owned equipment to researchers and high-volume manufacturers alike. Built on a commitment to long term trust and technical integrity, our mission has always been simple, to deliver reliable used and refurbished tools through direct engineering expertise.

Today, CSI Semi serves as a full service technical partner, providing complete turnkey solutions from initial tool de-installation to cleanroom ready commissioning. We buy, sell, and manage secondary capital assets across five main categories: Semiconductor Fabrication, Assembly & Packaging, PCB Manufacturing, Facilities Infrastructure, and hard to source Spare Parts. Moving far beyond digital listing brokerages, our engineering team manages the heavy lifting—precision rigging, secure international logistics, expert refurbishment, and cleanroom setup, giving you a single accountable partner on the ground. Whether you are expanding a pilot research lab, upgrading a production line, or liquidating surplus inventory, we protect your project timelines, mitigate supply chain risks, and maximise asset value. Above all, we are committed to making your asset experience a safe, seamless, and rewarding one.
