Abstract
$N_2$ has been one of the most useful gases in industrial application, for example, plasma ashing, surface cleaning and decomposition of pollution gases. In order to clarify $N_2$ plasma properties and increase practical applications, many experimental and theoretical investigations have been carried out until now on. In this papa, we examined the characteristics of $N_2$ RF Plasmas using one-dimensional fluid model. $N_2$ plasmas showed a double-layer structure in both sheath regions as the power source voltage becomes higher. Generally, a double-layer structure should be showed in electro-negative plasmas, but not in electro-postive plasmas such as $N_2$ discharge. However, most electrons in $N_2$ plasmas lost their energy by many excitation reactions in the near of both electrodes where electron collisions were actively executed and such continuous reactions during an RF period made this structure strong with increase of the power source voltage. The dependence of $N_2$ plasma properties on pressure was also discussed.
