A process for forming GaAs on a silicon substrate with very low levels of unintended silicon doping. First, a dielectric layer of silicon dioxide, silicon nitride, or both is grown or deposited on the substrate. Next, a window is opened in the dielectric layer exposing the silicon substrate in the regions in which the GaAs is to be formed.Web
