ABSTRACTIn this paper, a detailed reliability investigation is presented for ultra-thin tunneling (∼50 Å) oxides grown in N2O ambient using rapid thermal processing (RTP). These N2Oss-oxides are compared with oxides of identical thickness grown in O2 ambient by RTP. The reliability investigations include time-dependent dielectric breakdown as well as stress-induced leakage current in MOS capacitors with these gate dielectrics. Results show that ultra-thin N2O-oxides show much improved reliability as compared to oxide grown in O2 ambient.

ABSTRACTIn this paper, ultra thin CVD Ta2O5 stacked gate dielectrics (Teq∼14Å-22Å) was fabricated by in-situ RTP processing. The leakage current of Ta2O5 devices is 103× lower leakage current compared to SiO2 of identical thickness for devices with Teq between 18Å-22Å. While Teq<18Å, the leakage current follows same train and J∼10−3A/cm2 for Ta2O5 stacked gate dielectrics with Teq=14Å. Superior interface properties and reliability have been obtained.
