摘要: A method for inhibiting out-diffusion of dopants from polycrystalline or single crystal silicon substrates high speed semiconductor devices into metal silicide conductive layers disposed on the substrate comprises interposing a refractory nitride layer between doped and layer. Dopant is further retarded, contact resistance lowered, by adding thin substrate.
