摘要： A method for providing a dielectric film having enhanced adhesion and stability. The method includes a post deposition treatment that densifies the film in a reducing atmosphere to enhance stability if the film is to be cured ex-situ. The densification generally takes place in a reducing environment while heating the substrate. The densification treatment is particularly suitable for silicon-oxygen-carbon low dielectric constant films that have been deposited at low temperature.

摘要： 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.

摘要： An embodiment of the present invention provides methods for forming a carbon-containing layer having a low dielectric constant and good gap-fill capabilities. A method includes depositing a carbon-containing layer on a substrate and transforming the carbon-containing layer to remove at least some of the carbon. The transforming step may include annealing the carbon-containing layer in a furnace containing a hydrogen atmosphere, for example. The carbon-containing layer may be a carbon-doped silicon oxide material, where the transforming step changes the carbon-doped silicon oxide. Additionally, the method may include subjecting the annealed layer to a hydrogen and/or low oxygen plasma treatment to further remove carbon from the layer. Additionally, a step of adding a capping layer to the annealed, plasma treated material is provided. Products made by the above methods are also included, such as a product including a low k carbon-containing layer where the low k carbon-containing layer has been transformed to remove some of the carbon from the layer. An additional product includes a transformed carbon-containing layer further subjected to a hydrogen plasma treatment to remove more carbon from the layer. Further, a capping layer deposited over the transformed and hydrogen plasma treated layer is provided.

摘要： The present invention relates to the deposition of dielectric layers, and more specifically to a method and apparatus for forming dielectric layers such as borophosphosilicate glass (BPSG) having improved film uniformity, higher deposition rate, superior gap fill/reflow capability, and smoother surface morphology. The method forms a dielectric layer with a process using helium carrier gas that produces substantially less downstream residue than conventional methods and apparatus, thereby reducing the need for chamber cleaning and increasing throughput of processed wafers. The present invention utilizes helium instead of nitrogen as carrier gas in a process for forming a dielectric layer such as BPSG to provide various unexpected benefits. According to one aspect, the present invention forms a dielectric film on a substrate, and prolongs a period between chamber cleanings in a system by using helium which produces substantially less downstream and upstream residue than a process using nitrogen. The method includes introducing a process gas containing silicon, oxygen, and first dopant atoms into the chamber; using helium as the carrier gas in the system; and processing more substrates between cleanings than a process using nitrogen as carrier gas. A further aspect of the invention includes annealing the dielectric films formed on the substrates at a lower temperature than required by the process using nitrogen as carrier gas.
