Ultra Clean Holdings

Ultra Clean Holdings, Inc. (UCT) develops and supplies critical subsystems, components and parts for the semiconductor industry, alongside ultra-high purity cleaning and analytical services. Founded in 1991, the company traces its origins to bringing Japanese-developed ultra clean manufacturing techniques to the global market. It employs more than 6,000 people across locations in North America, Asia, Europe and the Middle East.

The work is organised into two divisions. The Products Division offers an integrated outsourced solution for major subassemblies, covering prototyping, design for manufacturability, high-precision manufacturing and the shortening of design-to-delivery cycle times. The Services Division performs tool chamber parts cleaning and coating for semiconductor manufacturers and includes ChemTrace, which provides micro-contamination analytical services.

Technical disciplines at UCT include ultra-clean manufacturing, contamination control, ultra-high purity cleaning, micro-contamination analysis, subassembly design and manufacturing, and cycle-time optimisation. The company's stated vision is to accelerate AI innovation with customers, turning concepts into global production delivered with speed, agility and trust, with an emphasis on stringent purity and quality standards for next-generation device manufacturing.

UCT's work reaches broadly across the electronics supply chain: it indirectly touches every semiconductor chip that goes into smartphones, smart cars and artificial intelligence devices. Its stated industry verticals include semiconductor fabrication, consumer electronics, automotive and AI devices.
