Abstract:
A method of building a semiconductor device, comprising:providing a silicon-containing portion of said semiconductor device, said semiconductor device 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 and having a silicon nitride film deposited as a final layer over at least a portion of said semiconductor device; performing a fabrication step in relation to a silicon-containing portion of said semiconductor device 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 and having a silicon nitride film deposited as a final layer over at least a portion of said semiconductor device; allowing an undesirable effect relating to said silicon-containing portion of said semiconductor device 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 and having a silicon nitride film deposited as a final layer over at least a portion of said semiconductor device to result from said fabrication step; and countering at least in part said undesirable effect with an introduction of a high-pressure hydrogen gas to said semiconductor device 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 and having a silicon nitride film deposited as a final layer over at least a portion of said semiconductor device.
