During silicide formation, unreacted NiPt metals is traditionally removed either by aqua regia (ESH concern) or SPM. This latter can easily degrade the device yield in HKMG (High K Metal Gate) nodes if the metal gates (usually TiN based) aren’t perfectly encapsulated. First some new characterizations are presented to better understand the NiPt metal alloy removal, then a new solution is given to be able to remove this alloy without degrading HKMG materials. |
