Ichor Holdings, Ltd is engaged in designing, engineering, and manufacturing of critical fluid delivery subsystems and components for semiconductor capital equipment. Its primary product offerings include gas and chemical delivery systems and subsystems, collectively known as fluid delivery systems and 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 systems and 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, electron beam (e-beam) and laser-welded components, precision vacuum and hydrogen brazing, and surface treatment technologies.
