Abstract:
Disclosed is a method of depositing a thin film on a substrate loaded in a chamber by chemical vapor deposition (CVD). Source gas including silicon-based gas and nitrogen-based gas is supplied into a chamber. Polycrystalline silicon is deposited on the substrate by the source gas. A mixing ratio of the nitrogen-based gas to the silicon-based gas may be less than 0.05. When the mixing ratio of the nitrogen-based gas is excessive, silicon nitride (SixNy) containing a large amount of silicon is deposited on the substrate. The silicon-based gas may be silane (SiH4) or disilane (Si2H6). The nitrogen-based gas may be ammonia (NH3). According to the method, polycrystalline silicon having very fine size can be deposited and degradation of characteristics can be prevented by improving evenness of electrical characteristic.
