    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.

    Abstract: A method for forming layers with silicon is disclosed. The layers may be created by positioning a substrate within a processing chamber, heating the substrate to a first temperature between 300 and 500° C. and introducing a first precursor into the processing chamber to deposit a first layer. The substrate may be heated to a second temperature between 400 and 600° C.; and, a second precursor may be introduced into the processing chamber to deposit a second layer. The first and second precursor may comprise silicon atoms and the first precursor may have more silicon atoms per molecule than the second precursor.

    Abstract: In accordance with some embodiments herein, methods and apparatuses for deposition of thin films are provided. In some embodiments, a deposition reactor is provided comprising: a first station configured to contain a substrate, the first station comprising a first heating element; a second station configured to contain the substrate, the second station comprising a second heating element, wherein the first station is configured to contact the substrate with a first reactant in the first station in substantial isolation from the second station such that a layer of the first reactant is deposited on the substrate, wherein the first heating element is configured to heat the first station to a first station temperature during contacting of the substrate with the first reactant, wherein the second station is configured to contact the substrate with a second reactant in the second station substantially in the absence of the first reactant, and wherein the second heating element is configured to heat the second station to a second station temperature during contacting of the substrate with the second reactant, a transfer system; and a controller set to control a cycle of: moving the substrate via the transfer system to the first station, directing the first station to contact the substrate with the first reactant at the first station temperature, moving the substrate to the second station via the transfer system, and directing the second station to contact the substrate with the second reactant at the second station temperature, and further set to repeat the cycle until a film of desired thickness is formed on a surface of the substrate.

    Abstract: In some embodiments, an oxide layer is grown on a semiconductor substrate by oxidizing the semiconductor substrate by exposure to hydrogen peroxide at a process temperature of about 500° C. or less. The exposure to the hydrogen peroxide may continue until the oxide layer grows by a thickness of about 1 Å or more. Where the substrate is a germanium substrate, while oxidation using H2O has been found to form germanium oxide with densities of about 4.25 g/cm3, oxidation according to some embodiments can form an oxide layer with a density of about 6 g/cm3 or more (for example, about 6.27 g/cm3). In some embodiments, another layer of material is deposited directly on the oxide layer. For example, a dielectric layer may be deposited directly on the oxide layer.

    Abstract: A process for depositing aluminum oxynitride (AlON) 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 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.
