    摘要: Densely spaced gates of field effect transistors usually lead to voids in a contact interlayer dielectric. If such a void is opened by a contact via and filled with conductive material, an electrical short between neighboring contact regions of neighboring transistors may occur. By forming a recess between two neighboring contact regions, the void forms at a lower level. Thus, opening of the void by contact vias is prevented.

    摘要: During the manufacture of advanced metallization systems, a dielectric cap layer formed on a sensitive dielectric material may be partially maintained during a CMP process for removing excess metal, thereby avoiding the necessity for depositing a dedicated etch stop material, as may be required in conventional approaches when substantially completely consuming the dielectric cap material during the CMP process. Hence, reduced process complexity and/or enhanced flexibility may be accomplished in combination with increased integrity of the low-k dielectric material.

    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.

    摘要: In a metallization system of a semiconductor device, a transition via may be provided with an increased degree of tapering by modifying a corresponding etch sequence. For example, the resist mask for forming the via opening may be eroded once or several times in order to increase the lateral size of the corresponding mask opening. Due to the pronounced degree of tapering, enhanced deposition conditions may be accomplished during the subsequent electrochemical deposition process for commonly filling the via opening and a wide trench connected thereto.
