It is a leader in the design, engineering and manufacturing of critical fluid delivery subsystems and components for semiconductor capital equipment. Its product offerings include gas and chemical delivery subsystems, collectively known as fluid delivery subsystems, which are key elements of the process tools used in the manufacturing of semiconductor devices. Its gas delivery subsystems deliver, monitor and control precise quantities of the specialized gases used in semiconductor manufacturing processes such as etch and deposition. Its chemical delivery subsystems precisely blend and dispense the reactive liquid chemistries used in semiconductor manufacturing processes such as chemical-mechanical planarization, electroplating, and cleaning. It also manufactures precision-machined components, weldments, and proprietary products for use in fluid delivery systems for direct sales to its customers, as well as certain components for internal use in fluid delivery systems and for direct sales to its customers. This vertically-integrated portion of its business is primarily focused on metal and plastic parts that are used in gas and chemical systems, respectively. It is headquartered in Fremont, CA.ichorsystems.com.
