Abstract
The formation of metal silicides in silicon nitride spacers on a gate electrode causes bridging between a gate electrode and the source and drain regions of a semiconductor device. The bridging is prevented by forming a thin layer of silicon oxide on the silicon nitride spacers prior to forming the metal silicide layers on the device.
