Chemical & Gas Delivery

Using state-of-the-art testing equipment and protocols developed by our engineering team, expert technicians ensure that our customers’ systems always meet their stringent performance requirements.

UCT’s chemical and gas delivery systems enable realization of Gordon Moore’s prediction about ever-shrinking transistors through our superior technical expertise in design and manufacturing. Our turnkey systems permit the precise delivery, management and control of specialty gasses and chemicals in semiconductor, flat panel and solar applications.

Chemical Delivery

Production of plastic chemical delivery systems has been the focus of UCT’s Fluid Delivery Solutions unit for more than 15 years. We address the complexity of repeatedly, reliable delivering of liquid chemicals and precursors while precisely meeting all equipment requirements. Our expert welders fabricate the small sub-systems our customers need as well as large all-plastic cabinets and exhaust ducting using state-of-the-art production methods.

UCT’s welding professionals routinely work with all forms of plastics including PP, PVC, CPVC, PVDF, PFA and other FM 4910-approved materials. We ensure the integrity of chemical delivery systems utilizing leading edge capabilities, including infrared welding and hot gas welding. Our welding process is certified with CSN 05 0705 (050705). The weldments are leak tested using Helium pressure and electrical permeability tests (spark tests). To ensure dimensional accuracy, fabricated parts are subject to digital 3D measurement inspection. 

Weldments are integrated by UCT’s highly skilled manufacturing team with necessary high-purity PFA pipe tubing and precision PFA tube bending. To deliver chemical delivery system modules and subsystems in clean and ready to install condition, the final integration is performed in our class 10,000/ISO 7 clean room.

Gas Delivery

From prototyping to delivering configurable gas delivery solutions with in-house design and testing capabilities, UCT is the semiconductor industry’s one-stop solution. We provide precise delivery, management and control of specialty gasses and chemicals in flat panel, solar applications. As the industry’s first turnkey gas delivery system manufacturer, UCT is a leader in enabling outsourcing strategies. Our business model was developed around the highly configurable nature of semiconductor equipment manufacturing.

In addition, UCT is a global leader in ultra-high purity (UHP) orbital and hand welding. Our rigorously trained and certified welding professionals apply the latest techniques and technologies to ensure perfect welds every time. Our broad range of capabilities includes small to large diameter fabrication, orbital welding, manual welding and precision tube bending. By combining robotics welding with hand craftsmanship, UCT has transformed the art of high-purity welding and orbital welding to a robust manufacturing science.

With final assembly in our class 100 and 1000 clean rooms and state-of-the-art inspection methods, UCT’s expert technicians ensure our customers’ gas delivery systems meet the stringent cleanliness requirements that today’s leading-edge processes require.
