Abstract

NiSi were formed from either Ni monolayer or Ni/Ti bilayer and the SADS method was applied to fabricated PMOSFET with Ni-polycide gate electrodes. PMOSFET made from Ni monolayer showed thermal stability unto 300~40$0^{\circ}C$ for 600sec., and excellent C-V characteristics for long time of drive-in anneal than PMOSFET made from Ni/Ti bilayer. This was attributed to easier decomposition and subsequent Ni diffusion to SiO$_2$ layer, probably due to the presence of Ti unreducing process
