Description

Ultra Clean Holdings, Inc. engineers, manufactures, and supplies essential components, sub-assemblies, and specialized purification and analytical services for the global semiconductor industry. The company operates both domestically in the United States and internationally. Their extensive product portfolio includes a comprehensive suite of high-purity components such as specialized valves, connectors, pneumatic actuators, manifolds, hoses, pressure gauges, safety solutions, and heating elements for gas lines. They also engineer specialized chemical delivery modules (CDMs), which precisely transport gases and reactive chemicals in both liquid and gaseous forms from a centralized subsystem to the reaction chamber. Furthermore, UCH provides advanced gas delivery systems (GDS), incorporating essential components like weldments, filters, mass flow controllers (MFCs), regulators, pressure transducers, and integrated electronic or pneumatic control systems. The company's range of offerings extends to industrial and automation production equipment, as well as sophisticated fluid delivery systems (FDS). These FDS integrate chemical delivery units, PFA tubing, filters, flow controllers, regulators, and electronic/pneumatic control systems. Additionally, UCH develops precision robotic systems, critical top-plate and frame assemblies, and process modules – which are vital subsystems of semiconductor manufacturing tools used to create integrated circuits on wafers – along with other high-level assemblies. Beyond products, UCH offers specialized cleaning and coating services for tool chambers. Their micro-contamination analysis services assess tool parts, wafers, depositions, chemicals, cleanroom materials, deionized water, and airborne molecular contamination. They also provide analytical verification services for process tool chamber cleaning. Ultra Clean Holdings primarily serves Original Equipment Manufacturers (OEMs) in the semiconductor capital equipment and integrated device manufacturing industries. Furthermore, their market reach extends to diverse sectors including display, consumer, medical, energy, industrial, and research equipment. Founded in 1991, the company maintains its headquarters in Hayward, California.
