摘要:
A method of forming an organosilicate layer is disclosed. The organosilicate layer is formed by applying an electric field to a gas mixture comprising an organosilane compound and an oxygen-containing gas. The organosilicate layer is compatible with integrated circuit fabrication processes. In one integrated circuit fabrication process, the organosilicate layer is used as an intermetal dielectric layer. In another integrated circuit fabrication process, the organosilicate layer is incorporated into a damascene structure.

A method of forming a low dielectric constant silicate material for use in integrated circuit fabrication processes is disclosed. The low dielectric constant silicate material is formed by reacting by reacting a gas mixture comprising an organosilane compound, an oxygen source, and an inert gas. Thereafter, a silicon carbide cap layer is formed on the silicate material by reacting a gas mixture comprising a silicon source and a carbon source. The silicon carbide cap layer protects the underlying organosilicate layer from cracking and peeling when it is hardened during a subsequent annealing step.

A method and apparatus for processing a substrate to form a feature in low k dielectric materials. One aspect of the invention provides a method for processing a substrate including forming a feature definition in a dielectric material deposited on a surface of a substrate, depositing one or more conductive materials to fill at least a portion of the feature definition, planarizing the substrate surface to expose the dielectric material, removing at least a portion of the dielectric material, and depositing a low k dielectric material.

Methods are provided for depositing an oxygen-doped dielectric layer. The oxygen-doped dielectric layer may be used for a barrier layer or a hardmask. In one aspect, a method is provided for processing a substrate including positioning the substrate in a processing chamber, introducing a processing gas comprising an oxygen-containing organosilicon compound, carbon dioxide, or combinations thereof, and an oxygen-free organosilicon compound to the processing chamber, and reacting the processing gas to deposit an oxygen-doped dielectric material on the substrate, wherein the dielectric material has an oxygen content of about 15 atomic percent or less. The oxygen-doped dielectric material may be used as a barrier layer in damascene or dual damascene applications.
摘要:
A method for processing semiconductor substrates by reacting hydroxyl radicals with a precursor to cause the precursor to decompose and form a film which deposits on a substrate. Hydroxyl radicals, which are produced in a hydroxyl-ion producing apparatus outside of a chemical vapor deposition reactor, are mixed with a precursor to form a hydroxyl ions-precursor mixture. The hydroxyl ions-precursor mixture is introduced into the chemical vapor deposition reactor.

A method of forming a silicon carbide layer for use in integrated circuit fabrication processes is provided. The silicon carbide layer is formed by reacting a gas mixture comprising a silicon source, a carbon source, and a dopant in the presence of an electric field. The as-deposited silicon carbide layer has a compressibility that varies as a function of the amount of dopant present in the gas mixture during later formation.
