    摘要: A method for preparing an interlayer dielectric to minimize damage to the interlayer's dielectric properties, the method comprising the steps of: depositing a layer of a silicon-containing dielectric material onto a substrate, wherein the layer has a first dielectric constant and wherein the layer has at least one surface; providing an etched pattern in the layer by a method that includes at least one etch process and exposure to a wet chemical composition to provide an etched layer, wherein the etched layer has a second dielectric constant, and wherein the wet chemical composition contributes from 0 to 40% of the second dielectric constant; contacting the at least one surface of the layer with a silicon-containing fluid; optionally removing a first portion of the silicon-containing fluid such that a second portion of the silicon-containing fluid remains in contact with the at least one surface of the layer; and exposing the at least one surface of the layer to UV radiation and thermal energy, wherein the layer has a third dielectric constant that is restored to a value that is at least 90% restored relative to the second dielectric constant.

    摘要: The present invention is a process for spin-on deposition of a silicon dioxide-containing film under oxidative conditions for gap-filling in high aspect ratio features for shallow trench isolation used in memory and logic circuit-containing semiconductor substrates, such as silicon wafers having one or more integrated circuit structures contained thereon, comprising the steps of: providing a semiconductor substrate having high aspect ratio features; contacting the semiconductor substrate with a liquid formulation comprising a low molecular weight aminosilane; forming a film by spreading the liquid formulation over the semiconductor substrate; heating the film at elevated temperatures under oxidative conditions. Compositions for this process are also set forth.
