Abstract :
TiN gate thin-film fully-depleted SOI CMOS devices were fabricated and discussed. Key process technologies were demonstrated. Compared with the dual polysilicon gate devices, the channel doping concentration of NMOS and PMOS can be reduced without changing the VT. This enhances the mobility. Symmetrical VT was achieved by nearly the same VT implant dose because of the near mid-gap workfunction of TiN gate.
