  • Patent number: 9837281
    Abstract: A process for depositing doped aluminum nitride (doped AlN) is disclosed. The process comprises 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 a dopant precursor to form doped AlN. The temporally separated exposures to an aluminum precursor and a nitrogen precursor, and the subsequent exposure to a dopant precursor together constitute a doped AlN deposition cycle. A plurality of doped AlN deposition cycles may be performed to deposit a doped AlN film of a desired thickness. The dopant content of the doped AlN can be tuned by performing a particular ratio of 1) separated exposures to an aluminum precursor and a nitrogen precursor, to 2) subsequent exposures to the dopant. The deposition may be performed in a batch process chamber, which may accommodate batches of 25 or more substrates.
