    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.

    摘要: Methods and structures for forming a contact hole structure are disclosed. These methods first form a substantially silicon-free material layer over a substrate. A material layer is formed over the substantially silicon-free material layer. A contact hole is formed within the substantially silicon-free material layer and the material layer without substantially damaging the substrate. In addition, a conductive layer is formed in the contact hole so as to form a contact structure.

    摘要: A plasma containing 5–10% oxygen and 90–95% of an inert gas strips photoresist from over a low-k dielectric material formed on or in a semiconductor device. The inert gas may be nitrogen, hydrogen, or a combination thereof, or it may include at least one of nitrogen, hydrogen, NH3, Ar, He, and CF4. The operating pressure of the plasma may range from 1 millitorr to 150 millitor. The plasma removes photoresist, the hard skin formed on photoresist during aggressive etch processes, and polymeric depositions formed during etch processes. The plasma strips photoresist at a rate sufficiently high for production use and does not appreciably attack carbon-containing low-k dielectric materials. An apparatus including a plasma tool containing a semiconductor substrate and the low oxygen-content plasma, is also provided.

    摘要: A method and system for determining the dielectric constant of a low-k dielectric film on a production substrate include measuring the electronic component of the dielectric constant using an ellipsometer, measuring the ionic component of the dielectric constant using an IR spectrometer, measuring the overall dielectric constant using a microwave spectrometer and deriving the dipolar component of the dielectric constant. The measurements and determination are non-contact and may be carried out on a production device that is further processed following the measurements.
