The distribution of the dopant between the various layers is of major concern. The effects of the fluorine incorporated during WSi 2 deposition have been discussed because fluorine may diffuse into the gate oxide. We have studied the redistribution of boron, phosphorus and fluorine in WSi 2 /poly/SiO 2 /poly/SiO 2 /Si (bulk) gate structures by using hot e-gas SNMS and nuclear analyses (RBS/NRA), in samples subjected to thermal treatments that simulate the different steps of the ULSI fabrication sequence.
