Abstract
Currently, for satisfying the needs of scaled MOSFET's a high quality thin oxide dielectric is desired because the properties of conventional $SiO_2$ film are not acceptable for these very small sized transistors. As an alternative gate dielectric have drawn considerable alternation due to their superior performance and reliability properties over conventional $SiO_2$, to obtain the superior characteristics of ultra thin dielectric films, $N_2O$ grown thin oxynitride has been proposed as a dielectric growtuanneal ambient. In this study the authors observed process characteristics of $N_2O$ grown thin dielectric. In view points of the process characteristics of MOS capacitor, the sheet resistance of 4.07$[\Omega/sq.]$, the film stress of $1.009e^{10}[dyne/cm^2]$, the threshold voltage$(V_t)$ of 0.39[V], the breakdown voltage(BV[V]) of 11.45[V] was measured in PMOS. I could achieve improved electrical characteristics and reliability for deep submicron MOSFET devices with $N_2O$ thin oxide.
