Larger wafer diameters provide more chips per wafer at a modest increase in material and process costs, resulting in reduced chip costs. Historically, transitions to larger diameter wafers have provided cost reductions greater than 20% per unit area. H
Manufacturing in Lehi, Utah We’re building a new 300-millimeter semiconductor wafer fabrication plant in Lehi, Utah, that will begin production as early as 2026. The new fab (LFAB2) currently under construction, will connect to our existing fab (LFAB1) in the heart of the Silicon Slopes....
