英文摘要For gate oxide thinned down to 1.9 and 1.4 nm, conventional methods of incorporating nitrogen (N) in the gate oxide might become insufficient in stopping,boron penetration and obtaining lower tunneling leakage. In this paper, oxynitride gate dielectric grown by oxidation of N-implanted silicon substrate has been studied. The characteristics of ultrathin gate oxynitride with equivalent oxide thickness (EOT) of 1.9 and 1.4 mn grown by this method were analyzed with MOS capacitors under the accumulation conditions and compared with pure gate oxide and gate oxide nitrided by N2O annealing. EOT of 1.9- and 1.4-nm oxynitride gate dielectrics grown by this method have strong boron penetration resistance, and reduce gate tunneling leakage current remarkably. High-performance 36-nm gate length CMOS devices and CMOS 32 frequency dividers embedded with 57-stage/201-stage CMOS ring oscillator, respectively, have been fabricated successfully, where the EOT of gate oxynitride grown by this method is 1.4 nm. At power supply voltage V-DD of 1.5 V drive current Ion of 802 muA/mum for NMOS and -487 muA/mum for PMOS are achieved at off-state leakage I-off of 3.5 nA/mum for NMOS and -3.0 nA/mum for PMOS.
