Abstract: Methods of depositing material onto a surface of a substrate. Exemplary methods include flowing a gas-phase precursor within the reaction chamber, condensing the precursor onto the surface of the substrate to form condensed material, and curing the condensed material to transform the condensed material to cured material. The step of curing can be a plasma process and can include use of a reactant.

Abstract: An oxide or nitride film containing carbon and at least one of silicon and metal is formed by ALD conducting one or more process cycles, each process cycle including: feeding a first precursor in a pulse to adsorb the first precursor on a substrate; feeding a second precursor in a pulse to adsorb the second precursor on the substrate; and forming a monolayer constituting an oxide or nitride film containing carbon and at least one of silicon and metal on the substrate by undergoing ligand substitution reaction between first and second functional groups included in the first and second precursors adsorbed on the substrate. The ligand may be a halogen group, —NR2, or —OR.

Abstract: A method for depositing an oxide film on a substrate by thermal ALD and PEALD, includes: providing a substrate in a reaction chamber; depositing a first oxide film on the substrate by thermal ALD in the reaction chamber; and without breaking a vacuum, continuously depositing a second oxide film on the first oxide film by PEALD in the reaction chamber.

Abstract: Methods and precursors for depositing silicon nitride films by atomic layer deposition (ALD) are provided. In some embodiments the silicon precursors 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%).

Abstract: In accordance with some embodiments herein, methods and apparatuses for flowable deposition of thin films are described. Some embodiments herein relate to cyclical processes for gap-fill in which deposition is followed by a thermal anneal and repeated. In some embodiments, the deposition and thermal anneal are carried out in separate station. In some embodiments second module is heated to a higher temperature than the first station. In some embodiments, the thermal anneal comprises RTA.
