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. The deposition may be performed without exposure to plasma.

The process comprises providing a plurality of semiconductor substrates in a batch process chamber and depositing an aluminum nitride layer on the substrates by performing a plurality of deposition cycles without exposing the substrates to plasma during the deposition cycles. Each deposition cycle comprises flowing an aluminum precursor pulse into the batch process chamber, removing the aluminum precursor from the batch process chamber, and removing the nitrogen precursor from the batch process chamber after flowing the nitrogen precursor and before flowing another pulse of the aluminum precursor. The process chamber may be a hot wall process chamber and the deposition may occur at a deposition pressure of less than 1 Torr.

Abstract: A chemical vapor deposition furnace for depositing silicon nitride films is disclosed. The furnace includes a process chamber elongated in a substantially vertical direction and a wafer boat for supporting a plurality of wafers in the process chamber. A process gas injector inside the process chamber is provided with vertically spaced gas injection holes to provide gas introduced at a feed end in an interior of the process gas injector to the process chamber. A valve system connected to the feed end of the process gas injector is being constructed and arranged to connect a source of a silicon precursor and a nitrogen precursor to the feed end for depositing silicon nitride layers. The valve system may connect the feed end of the process gas injector to a cleaning gas system to provide a cleaning gas to remove silicon nitride from the process gas injector and/or the process chamber.
