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: The disclosure relates to methods of depositing a material comprising silicon in a gap. The method comprises providing a substrate, the substrate comprising the gap, wherein the gap comprises an inner surface and exposing the substrate to a first plasma having high ion energy to modify predetermined areas of the gap inner surface. The method further comprises exposing the substrate to a second plasma having low ion energy to passivate the modified areas of the gap surface to form passivated modified areas on the gap surface and contacting the substrate with a vapor-phase silicon precursor to chemisorb the silicon precursor on unmodified areas of the gap for depositing material comprising silicon on the unmodified areas. The current disclosure further relates to a method of controlling chemisorption of a vapor-phase silicon precursor on a substrate, and to a semiconductor processing assembly for performing the methods according to the current disclosure.

Abstract: The current disclosure relates to a vapor deposition assembly for depositing silicon nitride on a substrate by a plasma-enhanced cyclic deposition process. The disclosure also relates to a method for depositing silicon nitride on a substrate by a plasma-enhanced cyclic deposition process. The method comprises providing a substrate in a reaction chamber, providing a vapor-phase silicon precursor according to the formula SiH3X, wherein X is iodine or bromine, into the reaction chamber, removing excess silicon precursor and possible reaction byproducts from the reaction chamber and providing a reactive species generated from a nitrogen-containing plasma into the reaction chamber to form silicon nitride on the substrate. The disclosure further relates to structure and devices formed by the method.
