Ichor Holdings, Ltd. is engaged in the design, engineering and manufacturing of fluid delivery subsystems for semiconductor capital equipment. The Company's primary offerings include gas and chemical delivery subsystems, collectively known as fluid delivery subsystems. Its gas delivery systems consist of gas lines, each controlled by a series of mass flow controllers, regulators, pressure transducers and valves, and an integrated electronic control system. Its gas delivery subsystems are used in equipment for dry manufacturing processes, such as etch, physical vapor deposition, epitaxy and strip. Its chemical delivery subsystems are used to precisely blend and dispense reactive chemistries and colloidal slurries critical to the specific wet front-end process, such as wet clean, electro chemical deposition (ECD) and chemical-mechanical planarization (CMP). It manufactures various components for internal use in fluid delivery systems and for direct sales to its customers.
