The present invention relates to a method for manufacturing a ferroelectric field-effect transistor, particularly to a ferroelectric field-effect transistor with a metal/ferroelectric/insulator/semiconductor (MFIS) gate capacitor structure. The method comprises steps of depositing a bismuth layered ferroelectric film on the insulator buffered Si, after a high-temperature thermal treatment, depositing an upper electrode on the bismuth layered ferroelectric film.

This invention proposes a method for making very low threshold voltage (Vt) metal-gate/high-κ CMOSFETs using novel self-aligned low-temperature ultra shallow junctions with gate-first process compatible with VLSI. At 1.2 nm equivalent-oxide thickness (EOT), good effective work-function of 5.3 and 4.1 eV, low Vt of +0.05 and 0.03 V, high mobility of 90 and 243 cm2/Vs, and small 85° C. bias-temperature-instability <32 mV (10 MV/cm, 1 hr) are measured for p- and n-MOS.
