    摘要: In a manufacturing sequence for forming metallization levels of semiconductor devices, out-gassing of volatile components after an etch process may be initiated immediately after the etch process, thereby reducing the probability of creating contaminants in other substrates and transport carriers during transport activities. Consequently, the defect rate of deposition-related irregularities in the metallization level may be reduced.

    摘要: By forming metal capacitors in the metallization structures of semiconductor devices, complex manufacturing sequences in the device level may be avoided. The process of manufacturing the metal capacitors may be performed on the basis of well-established patterning regimes of modern metallization systems by using appropriately selected etch stop materials, which may enable a high degree of compatibility for forming via openings in a metallization layer while providing a capacitor dielectric of a desired high dielectric constant in the capacitor.
