By performing sophisticated anneal techniques, such as laser anneal, flash
anneal and the like, for a metal silicide formation, such as nickel
silicide, the risk of nickel silicide defects in sensitive device
regions, such as SRAM pass gates, may be significantly reduced. Also, the
activation of dopants may be performed in a highly localized manner, so
that undue damage of gate insulation layers may be avoided when
activating and re-crystallizing drain and source regions.
