About

Established in 2009 as a Lam Research company, it operates facilities in Eaton and Springfield, Ohio, with 625,000 square feet across both sites. Its scale is matched by unusually fine control, including micro-machined holes and finishes below one micro-inch Ra, for components that help produce the electronics used every day.
