Abstract: An ALD method includes exposing a substrate to a first precursor including a plurality of different ligands, chemisorbing a precursor monolayer on the substrate, and reacting a second precursor with the precursor monolayer to yield a product monolayer. A surface reactive ligand exhibits a chemisorption affinity that exceeds the chemisorption affinity exhibited by a gas reactive ligand. Another deposition method includes exposing a substrate to a precursor containing an amino and/or imino ligand and a halide ligand and depositing a layer. The precursor exhibits a volatility that exceeds the volatility with a halide ligand taking the place of each amino and/or imino ligand. The precursor exhibits a thermal stability that exceeds the thermal stability with an amino and/or imino ligand taking the place of each halide ligand. The layer may exhibit less halogen content than with a halide ligand taking the place of each amino and/or imino ligand.

Abstract: This invention includes methods of forming a phosphorus doped silicon dioxide comprising layers, and methods of forming trench isolation in the fabrication of integrated circuitry. In one implementation, a method of forming a phosphorus doped silicon dioxide comprising layer includes positioning a substrate within a deposition chamber. First and second vapor phase reactants are introduced in alternate and temporally separated pulses to the substrate within the chamber in a plurality of deposition cycles under conditions effective to deposit a phosphorus doped silicon dioxide comprising layer on the substrate. One of the first and second vapor phase reactants is PO(OR)3 where R is hydrocarbyl, and an other of the first and second vapor phase reactants is Si(OR)30H where R is hydrocarbyl.

Abstract: A preferred embodiment of the invention is directed to support structures such as spacers used to provide a uniform distance between two layers of a device. In accordance with a preferred embodiment, the spacers may be formed utilizing flow-fill deposition of a wet film in the form of a precursor such as silicon dioxide. Formation of spacers in this manner provides a homogenous amorphous support structure that may be used to provide necessary spacing between layers of a device such as a flat panel display.
