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.

摘要： The present invention provides systems, methods and apparatus for high temperature (at least about 500-800.degree. C.) processing of semiconductor wafers. The systems, methods and apparatus of the present invention allow multiple process steps to be performed in situ in the same chamber to reduce total processing time and to ensure high quality processing for high aspect ratio devices. Performing multiple process steps in the same chamber also increases the control of the process parameters and reduces device damage. In particular, the present invention can provide high temperature deposition, heating and efficient cleaning for forming dielectric films having thickness uniformity, good gap fill capability, high density, low moisture, and other desired characteristics.

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 for providing a dielectric film having a low dielectric constant. The deposited film is particularly useful as an intermetal or premetal dielectric layer in an integrated circuit. The low dielectric constant film is a carbon-doped silicon oxide layer deposited from a thermal, as opposed to plasma, CVD process. The layer is deposited from a process gas of ozone and an organosilane precursor having at least one silicon-carbon (Si—C) bond. During the deposition process the wafer is heated to a temperature less than 250° C. and preferably to a temperature between 100-200° C. Enhancements to the process include adding Boron and/or Phosphorus dopants, two step deposition, and capping the post cured layer.
