What We Do

We are a leader in the design, engineering, and manufacturing of critical fluid delivery subsystems and components for semiconductor capital equipment. Our 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. Our gas delivery subsystems deliver, monitor, and control precise quantities of the specialized gases used in semiconductor manufacturing processes such as etch and deposition. Our 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. We also provide precision-machined components, weldments, e‑beam and laser-welded components, precision vacuum and hydrogen brazing and surface treatment technologies, and other proprietary products. This vertically integrated portion of our business is primarily focused on metal and plastic parts that are used in gas and chemical systems, respectively. We are strategically located to provide the highest level of customer service and support from our program management, sales, engineering, and executive management teams. Ichor is headquartered in Fremont, California, and we have production facilities in California, Oregon, Texas, Nevada, Minnesota, Singapore, Malaysia, Korea, Mexico, and the UK, staffed by our 2000+ team members.
