Abstract: A multiple-layer method for forming material within a gap on a surface of a substrate is disclosed. An exemplary method includes forming a layer of first material overlying the substrate and forming a layer of second (e.g., initially flowable) material within a region of the first material to thereby at least partially fill the gap with material in a seamless and/or void less manner.

Abstract: There is provided a method of filling one or more recesses by providing the substrate in a reaction chamber and introducing a first reactant to the substrate with a first dose, introducing a second reactant to the substrate with a second dose, wherein the first and the second doses overlap in an overlap area where the first and second reactants react and leave an initially substantially unreacted area where the first and the second areas do not overlap; introducing a third reactant to the substrate with a third dose, the third reactant reacting with the first or second reactant to form deposited material; and etching the deposited material. An apparatus for filling a recess is also disclosed.

Abstract: Methods and precursors for forming silicon nitride films are provided. In some embodiments, silicon nitride can be deposited by atomic layer deposition (ALD), such as plasma enhanced ALD. In some embodiments, deposited silicon nitride can be treated with a plasma treatment. The plasma treatment can be a nitrogen plasma treatment. In some embodiments the silicon precursors for depositing the silicon nitride comprise an iodine ligand. The silicon nitride films may have a relatively uniform etch rate for both vertical and the horizontal portions when deposited onto three-dimensional structures such as FinFETS or other types of multiple gate FETs. In some embodiments, various silicon nitride films of the present disclosure have an etch rate of less than half the thermal oxide removal rate with diluted HF (0.5%). In some embodiments, a method for depositing silicon nitride films comprises a multi-step plasma treatment.

Abstract: The current disclosure relates to methods of depositing silicon-containing material on a substrate comprising a gap, wherein the method comprises providing the substrate in a reaction chamber and depositing a carbon-containing inhibition layer on the substrate, and depositing silicon-containing material on the substrate. Depositing the inhibition layer comprises supplying a carbon precursor comprising carbon in the reaction chamber and supplying first plasma in the reaction chamber to form a first reactive species from the carbon precursor for forming the inhibition layer on the substrate. The inhibition layer is deposited preferentially in the vicinity of the top of the gap. The disclosure further relates to methods of forming a structure, methods of manufacturing a device and to a semiconductor processing apparatus.

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: Atomic layer deposition (ALD) processes for forming Group VA element containing thin films, such as Sb, Sb—Te, Ge—Sb and Ge—Sb—Te thin films are provided, along with related compositions and structures. Sb precursors of the formula Sb(SiR1R2R3)3 are preferably used, wherein R1, R2, and R3 are alkyl groups. As, Bi and P precursors are also described. Methods are also provided for synthesizing these Sb precursors. Methods are also provided for using the Sb thin films in phase change memory devices.
