    摘要: An intermediate structure from which a dual damascene structure may be fabricated includes a first-formed, unfaceted via hole and an intersecting trench both formed by gas plasma etching of a dielectric layer. The sidewall of the via hole is maintained unfaceted during and after trench formation by substantially filling it with a gas-plasma-etchable plug prior to trench formation. The presence of the plug in the via hole during gas plasma etching of the trench, also produces a trench bottom that is substantially flat.

    摘要: A method of reducing a charge on a substrate to prevent an arcing incident in a subsequent etch process is described. A patterned substrate is fastened to a chuck in a process chamber. A discharge process is performed that includes the three steps of (a) coupling the chuck to a 0 volt connection, (b) generating a plasma, and (c) coupling the chuck to a high voltage connection. The three steps are carried out in any sequence. An inert gas or an inert gas and an etching gas are flowed into the chamber during the discharge sequence. Alternatively, a fluorocarbon CXFYHZ or a fluorocarbon and a gas such as O2, H2, N2, N2O, CO, CO2, He or Ar is flowed into the chamber during the discharge sequence. The method is compatible with batch or single wafer processes and is extendable to etching low k dielectric layers with poor thermal conductivity.

    摘要: A plasma processing operation uses a gas mixture of N2 and H2 to both remove a photoresist film and treat a low-k dielectric material. The plasma processing operation prevents degradation of the low-k material by forming a protective layer on the low-k dielectric material. Carbon from the photoresist layer is activated and caused to complex with the low-k dielectric, maintaining a suitably high carbon content and a suitably low dielectric constant. The plasma processing operation uses a gas mixture with H2 constituting at least 10%, by volume, of the gas mixture.
