Ichor Holdings Ltd. engages in designing, engineering, and manufacturing fluid delivery subsystems for semiconductor capital equipment. The company is headquartered in Fremont, California and currently employs 1,820 full-time employees. The company went IPO on 2016-12-09. Its product includes 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. The company offers precision-machined components, weldments, electron beam and laser-welded components, precision vacuum and hydrogen brazing and surface treatment technologies and other proprietary products.
