In this Paper
Thermally reactive CoSi2 films with smooth interface and low resistivity by FA and RTA were introduced. The XRD
AES
TEM (cross-section)
SEM and Four-point probe tecniques were used to analyze the reactions between Co and Si as well as Co and SiO2
electroconduc-tivity of CoSi2 films
interface morphologies of CoSi2/Si and CoSi2/SiO2 structures. The results show that CoSi2 can be applied to self-aligned technology like TiSi2.
