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.
