    Abstract: There is provided a method of filling one or more gaps by providing the substrate in a reaction chamber and introducing a first reactant to the substrate with a first dose, thereby forming no more than about one monolayer by the first reactant on a first area; introducing a second reactant to the substrate with a second dose, thereby forming no more than about one monolayer by the second reactant on a second area of the surface, wherein the first and the second areas overlap in an overlap area where the first and second reactants react and leave an initially unreacted area where the first and the second areas do not overlap; and, introducing a third reactant to the substrate with a third dose, the third reactant reacting with the first or second reactant remaining on the initially unreacted area.

    Abstract: An etch stop layer comprises a metal oxide comprising a metal selected from the group consisting of metals of Group 4 of the periodic table, metals of Group 5 of the periodic table, metals of Group 6 of the periodic table, and yttrium. The metal oxide forms exceptionally thin layers that are resistant to ashing and HF exposure. Subjecting the etch stop layer to both ashing and HF etch processes removes less than 0.3 nm of the thickness of the etch stop layer, and more preferably less than 0.25 nm. The etch stop layer may be thin and may have a thickness of about 0.5-2 nm. In some embodiments, the etch stop layer comprises tantalum oxide (TaO).

    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.

    Abstract: Methods of depositing boron and carbon containing films are provided. In some embodiments, methods of depositing B, C films with desirable properties, such as conformality and etch rate, are provided. One or more boron and/or carbon containing precursors can be decomposed on a substrate at a temperature of less than about 400° C. One or more of the boron and carbon containing films can have a thickness of less than about 30 angstroms. Methods of doping a semiconductor substrate are provided. Doping a semiconductor substrate can include depositing a boron and carbon film over the semiconductor substrate by exposing the substrate to a vapor phase boron precursor at a process temperature of about 300° C. to about 450° C., where the boron precursor includes boron, carbon and hydrogen, and annealing the boron and carbon film at a temperature of about 800° C. to about 1200° C.
