摘要
This paper demonstrates characteristics of Al2O3 gate dielectric prepared by atomic layer deposition (ALD) for giga scale CMOS DRAM devices. Interface state density similar to 7x10(10) eV(-1)cm(2) near the midgap and excellent reliability with a low gate leakage current were attained from Al2O3/Si MOS system, p/nMOSFETs characteristics in terms of current drivability, transconductance (Gm), and subthreshold swing are described.
