    摘要: Embodiments of the present invention provide methods, apparatuses, and devices related to chemical vapor deposition of silicon oxide. In one embodiment, a single-step deposition process is used to efficiently form a silicon oxide layer exhibiting high conformality and favorable gap-filling properties. During a pre-deposition gas flow stabilization phase and an initial deposition stage, a relatively low ratio of silicon-containing gas:oxidant deposition gas is flowed, resulting in formation of highly conformal silicon oxide at relatively slow rates. Over the course of the deposition process step, the ratio of silicon-containing gas:oxidant gas is increased, resulting in formation of less-conformal oxide material at relatively rapid rates during later stages of the deposition process step.

The methods may include the steps of providing a substrate to a deposition chamber, generating an atomic oxygen precursor outside the deposition chamber, and introducing the atomic oxygen precursor into the chamber. The methods may also include introducing a silicon precursor to the deposition chamber, where the silicon precursor and the atomic oxygen precursor are first mixed in the chamber. The silicon precursor and the atomic oxygen precursor react to form the silicon oxide layer on the substrate, and the deposited silicon oxide layer may be annealed.

    摘要: A method to form a silicon oxide layer, where the method includes the step of providing a continuous flow of a silicon-containing precursor to a chamber housing a substrate, where the silicon-containing precursor is selected from TMOS, TEOS, OMTS, OMCTS, and TOMCATS. The method may also include the steps of providing a flow of an oxidizing precursor to the chamber, and causing a reaction between the silicon-containing precursor and the oxidizing precursor to form a silicon oxide layer. The method may further include varying over time a ratio of the silicon-containing precursor:oxidizing precursor flowed into the chamber to alter a rate of deposition of the silicon oxide on the substrate.
