Abstract:
A processing method for a workpiece of semiconductor material, said workpiece having at least one transistor gate structure having at least one first film of silicon nitride and having a second silicon nitride film deposited as a layer over at least a portion of said workpiece, comprising:placing said workpiece in a region having an ambient pressure of a gas, said workpiece having at least one trransisitor gate structure having at least one first film of silicon nitride and having a second silicon nitride film deposited as a layer over at least a portion of said workpiece; providing a forming gas in said region; and annealing said workpiece within said region in said forming gas, a pressure of said forming gas being greater than said ambient pressure of said gas in said region, said workpiece having at least one transistor gate structure having at least one first film of silicon nitride and having a second silicon nitride film deposited as a layer over at least a portion of said workpiece.
