    摘要: An integrated in situ etch process performed in a multichamber substrate processing system having first and second etching chambers. The process includes transferring a substrate having formed thereon in a downward direction a patterned photoresist mask, a dielectric layer, a stop layer and a feature in the substrate to be contacted into the first etching chamber to etch the dielectric layer. The substrate is then transferred from the first etching chamber to the second etching chamber under vacuum conditions and, in the second etching chamber, is exposed to an oxygen plasma or similar environment to strip away the photoresist mask deposited over the substrate. After the photoresist mask is stripped, the stop layer is etched through to the feature to be contacted in either the second or a third etching chamber of said multichamber substrate processing system. All three etching steps are performed in a system level in situ process so that the substrate is not exposed to an ambient between steps.

    摘要: A variety of techniques may be employed alone or in combination to reduce the incidence of defects arising in dielectric stack structures formed by chemical vapor deposition (CVD). Incidence of a first defect type attributable to reaction between an unreacted species of a prior CVD step and reactants of a subsequent CVD step, is reduced by exposing a freshly-deposited dielectric layer to a plasma before any additional layers are deposited. Incidence of a second defect type attributable to the presence of incompletely vaporized CVD liquid precursor material, is reduced by exposing the freshly-deposited dielectric layer to a plasma, and/or by continuing the flow of carrier gas through an injection valve for a period beyond the conclusion of the CVD step.

    摘要: An oxide and an oxynitride films and their methods of fabrication are described. The oxide or the oxynitride film is grown on a substrate that is placed in a deposition chamber. A silicon source gas (or a silicon source gas with a nitridation source gas) and an oxidation source gas are decomposed in the deposition chamber using a thermal energy source. A silicon oxide (or an oxynitride) film is formed above the substrate wherein total pressure for the deposition chamber is maintained in the range of 50 Torr to 350 Torr and wherein a flow ratio for the silicon source gas (or the silicon source gas with the nitridiation source gas) and the oxidation source gas is in the range of 1:50 to 1:10000 during a deposition process.
