Silfex makes precision silicon components for the semiconductor equipment industry, growing and machining the material used in processes ranging from plasma etching to thin-film deposition. 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.

• QQEQQE has been shaping high-purity quartz in Ohio since 1969, when its predecessor, Behm Glass, cut the state’s first fused quartz ingot for General Electric. Today, the company supplies precision quartz components to semiconductor manufacturers and other high-tech industries from two U.S. production sites, including a 110,000-square-foot Beavercreek facility. Its long experience carries from prototype work through high-volume production.DAYTON, OH

  Silicon Materials, IncFounded in Pittsburgh in 1992, Silicon Materials, Inc. makes electronic-grade silicon wafers for semiconductor manufacturers, using virgin polysilicon rather than scrap as the starting feedstock. The company is vertically integrated, with production in Pinsk, Belarus, U.S. sales and distribution, and traceability from polysilicon lot through final packaging. Its quality system is ISO 9001:2015 certified, and its facility produces as many as 60,000 wafers per month at adjusted 100mm capacity.334413GLENSHAW, PA
