Annealing films of previously annealed tungsten silicide (WSi2) in a non-oxidizing ambient (e.g. argon) at elevated temperature for a short time following reactive ion etching (RIE) and before any oxidizing treatment avoids occurence of irregular film edge oxidation and catastrophic failure of narrow WSi2 lines during any subsequent oxidizing treatment.
