Abstract :
We report low-threshold-voltage (Vt) TaN/HfLaO n-MOSFETs using solid-phase-diffusion (SPD)-formed junctions at a low temperature of 650 degC. The gate-first and self-aligned TaN/HfLaO n-MOSFETs using Ni/Sb SPD-formed source-drain junctions showed a low Vt of 0.16 V and a peak electron mobility of 187 cm2/V middots at a small 1.3-nm equivalent oxide thickness.
