A method for depositing aluminum oxynitride (AlON) is disclosed. The method comprises a step of subjecting a substrate to temporally separated exposures to an aluminum precursor and a nitrogen precursor to form an aluminum and nitrogen-containing compound on the substrate. The aluminum and nitrogen-containing compound is subsequently exposed to an oxygen precursor to form AlON. The temporally separated exposures to an aluminum precursor and a nitrogen precursor, and the subsequent exposure to an oxygen precursor together constitute an AlON deposition cycle. A plurality of AlON deposition cycles may be performed to deposit an AlON film of a desired thickness. The deposition may be performed in a batch process chamber, which may accommodate batches of 25 or more substrates. The deposition may be performed without exposure to plasma. |
