    摘要: A method of filling a gap formed between adjacent raised surfaces on a substrate. In one embodiment the method comprises depositing a boron-doped silica glass (BSG) layer over the substrate to partially fill the gap using a thermal CVD process; exposing the BSG layer to a steam ambient at a temperature above the BSG layer's Eutectic temperature; removing an upper portion of the BSG layer by exposing the layer to a fluorine-containing etchant; and depositing an undoped silica glass (USG) layer over the BSG layer to fill the remainder of the gap.

    摘要: A chemical vapor deposition method for forming a dielectric material in a trench formed on a substrate, where the method includes the steps of generating water vapor by contacting hydrogen gas and oxygen gas with a water vapor generation catalyst, and providing the water vapor to the process chamber. The method also includes flowing a silicon-containing precursor into the process chamber housing the substrate, flowing an oxidizing gas into the chamber, and causing a reaction between the silicon-containing precursor, the oxidizing gas and the water vapor to form the dielectric material in the trench. The method may also include increasing over time a ratio of the silicon-containing precursor to the oxidizing gas flowed into the chamber to alter a rate of deposition of the dielectric material.

    摘要: A method of filling a gap defined by adjacent raised features on a substrate includes providing a flow of a silicon-containing processing gas to a chamber housing the substrate and providing a flow of an oxidizing gas to the chamber. The method also includes depositing a first portion of a film as a substantially conformal layer in the gap by causing a reaction between the silicon-containing processing gas and the oxidizing gas. Depositing the conformal layer includes varying over time a ratio of the (silicon-containing processing gas):(oxidizing gas) and regulating the chamber to a pressure in a range from about 200 torr to about 760 torr throughout deposition of the conformal layer. The method also includes depositing a second portion of the film as a bulk layer. Depositing a second portion of the film includes maintaining the ratio of the (silicon-containing processing gas):(oxidizing gas) substantially constant throughout deposition of the bulk layer and regulating the chamber to a pressure in a range from about 200 torr to about 760 torr throughout deposition of the bulk layer. The method also includes exposing the substrate to nitrous oxide at a temperature less than about 900° C. to anneal the deposited film.
