    • Novel silicon precursors for low temperature deposition of silicon films are described herein. The disclosed precursors possess low vaporization temperatures, preferably less than about 500° C. In addition, embodiments of the silicon precursors incorporate a —Si—Y—Si— bond, where Y may comprise an amino group, a substituted or unsubstituted hydrocarbyl group, or oxygen. In an embodiment a silicon precursor has the formula: where Y is a hydrocarbyl group, a substituted hydrocarbyl group, oxygen, or an amino group; R1, R2, R3, and R4 are each independently a hydrogen group, a hydrocarbyl group, a substituted hydrocarbyl group, a heterohydrocarbyl group, wherein R1, R2, R3, and R4 may be the same or different from one another; X1, X2, X3, and X4 are each independently, a hydrogen group, a hydrocarbyl group, a substituted hydrocarbyl group, or a hydrazino group, wherein X1, X2, X3, and X4 may be the same or different from one another.
