Improvement of surface carrier mobility of HfO2 MOSFETs by high-temperature forming gas annealing.

Improvement of surface carrier mobility of HfO2 MOSFETs by high-temperature forming gas annealing.

The surface electron mobility of HfO2 NMOSFETs with a polysilicon gate electrode was studied in terms of the effects of high-temperature forming gas (FG) annealing. The high-temperature FG annealing significantly improved the drive current or the surface electron mobility of the NMOSFETs. Improvemen...
