Advanced FinFET CMOS Technology: TiN-Gate, Fin-Height Control and Asymmetric Gate Insulator Thickness 4T-FinFETs

We have successfully developed the advanced FinFET fabrication processes for materializing FinFET CMOS circuits. Using the developed technologies, we demonstrate the advanced TiN metal gate, fin-height controlled FinFET CMOS inverter with an excellent transfer performance, and the flexible threshold voltage, asymmetric gate insulator thickness four-terminal (4T) FinFET with a greatly improved subthreshold (S) slope, for the first time.
