Abstract
Silicon Nitride thin films were deposited on p-type Si (100) substrates by atomic layer deposition (ALD) method at $550^{\circ}C$ using alternating exposures of $SiH_2Cl_2$ and $NH_3$, and the physical and electrical propeties of the deposited films were characterized. The thickness of the films was linearly increased with the number of deposition cycles, and the growth rate of the films was 0.13 nm/cycle with the reactant exposures of $3.0\times10^{9}$ L. The silicon nitride thin films deposited by Alf exhibited similar physical properties with the silicon nitride thin films deposited by low-pressure chemical vapor deposition (LPCVD) method in terms of refractive index and wet etch rate, lowering deposition temperature by more than 200 $^{\circ}C$. The ALD films showed the leakage current density of 0.79 nA/$\textrm{cm}^2$ at 3 MV/cm, which is lower than 6.95 nA/$\textrm{cm}^2$ of the LPCVD films under the same condition.
