Abstract:
A processing method for a semiconductor workpiece having at least one transistor gate structure having a film of silicon nitride used as at least one of a sidewall spacer and a capping layer for a field-effect transistor gate located on a portion thereof, comprising:providing a semiconductor workpiece having at least one transistor gate structure having a film of silicon nitride used as at least one of a sidewall spacer and a capping layer for a field-effect transistor gate located on a portion thereof, said silicon nitride film deposited as a final layer over at least a portion of said semiconductor workpiece; and annealing said semiconductor workpiece in a forming gas at a pressure greater than an ambient pressure, said workpiece having at least one transistor gate structure having a film of silicon nitride used as at least one of a sidewall spacer and a capping layer for a field-effect transistor gate located on a portion thereof, wherein said step of annealing said semiconductor workpiece comprises annealing said semiconductor workpiece in said forming gas at a pressure substantially ranging from about 10 to about 25 atmospheres.
