Claim 0:
1. A cyclical deposition method comprising:
providing a substrate within a reaction chamber; and
depositing a layer comprising silicon oxide on the substrate, wherein a deposition cycle comprises:
providing a first silicon precursor to the reaction chamber to form chemisorbed species;
providing a second silicon precursor that reacts with the chemisorbed species;
providing a reactant; and

after the step of providing the second silicon precursor, forming a plasma using the reactant,
wherein the first silicon precursor comprises two or more ligands independently selected from the group consisting of —NR2 ligands, wherein each R of each NR2 ligand is independently selected from the group consisting of —CH3, —CH2CH3, —CH2CH2CH3, —CH2CH2CH2CH3, isopropyl (—CH(CH3)2), isobutyl, sec-butyl, tert-butyl, -SiH3, -Si(CH3)3, and H, where for at least one —NR2 ligand, if a first R═H, the second R≠H, and
wherein the second silicon precursor comprises at least one independently selected —OR ligand selected from the group consisting of hydroxide (—OH), alkoxy (—OCxHy—), and siloxy (—OSiCwHz—), where x is between 1 and 8, y is between 3 and 11, w is between 3 and 24, and z is between 9 and 33.
