Claim 10:
11. 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;
providing a second silicon precursor; and
providing a non-reactant active species formed using a plasma,

wherein the first silicon precursor comprises two or more ligands independently selected from the group consisting of —NR2 ligands, wherein each R of each NR2ligand is independently selected from the group consisting of —CH3, —CH2CH3, —CH2 CH2CH3, —CH2CH2CH3, 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 two or more ligands independently selected from the group consisting of —OR ligands 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.
