    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 disclosure relates to methods of filling gaps in semiconductor substrates. A method of filling a gap is disclosed. The method including providing a substrate having a gap in a reaction chamber, providing a first precursor including silicon and carbon into the reaction chamber in a vapor phase, wherein the first precursor includes at least one unsaturated carbon-carbon bond and at least one atom selected from oxygen and nitrogen. The method further includes providing a first plasma into the reaction chamber to polymerize the first precursor for forming a gap filling material, thereby at least partially filling the gap with the gap filling material. In some embodiments, the at least one unsaturated bond is a double bond.

    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.
