Ichor Holdings, Ltd. is engaged in designing, engineering, and manufacturing critical fluid delivery subsystems and components primarily for semiconductor capital equipment, as well as other industries, such as defense/aerospace and medical. The Company's primary 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 provides precision-machined components, weldments, e-beam and laser welded components, precision vacuum, and other products.
