Thus WebbTiCl4 and NH3 are mostly used as the Ti precursor and nitrogen source for the TiN ALD process. Unfortunately, the resistivities of TiN films increase with decreasing ALD process temperature. The resistivity of TiN films especially increases substantially (>150 μΩ·cm) at an ALD process temperature lower than 400 °C because of the remaining Cl impurities …
