摘要:
By providing a surface modification process prior to or during a self-limiting deposition process, the per se highly conformal deposition behavior may be selectively changed so as to obtain reliable coverage at specific surface areas, while significantly reducing or suppressing a deposition above unwanted surface areas, such as the bottom of a via in advanced metallization structures of highly scaled semiconductor devices.

By forming metallization structures on the basis of an imprint technique, in which via openings and trenches may be commonly formed, a significant reduction of process complexity may be achieved due to the omission of at least one further alignment process as required in conventional process techniques. Furthermore, the flexibility and efficiency of imprint lithography may be increased by providing appropriately designed imprint molds in order to provide via openings and trenches exhibiting an increased fill capability, thereby also improving the performance of the finally obtained metallization structures with respect to reliability, resistance against electromigration and the like.

By providing a plurality of resistors and a plurality of test patterns within a leakage current test structure, the number of probe pads required for estimating the plurality of test patterns may be significantly reduced, wherein, in some illustrative embodiments, several test patterns may be simultaneously assessed on the basis of two probe pads. Consequently, process parameters and/or design parameters for manufacturing metallization structures of semiconductor devices may be efficiently monitored and controlled.

摘要:
By forming a metal line extending through the entire interlayer dielectric material in resistance sensitive metallization layers, enhanced uniformity of these metallization layers may be obtained. The patterning of respective via openings may be accomplished on the basis of a recess formed in a cap layer, which additionally acts as an efficient etch stop layer during the patterning of the trenches, which extend through the entire interlayer dielectric material. Consequently, for a given design width of metal lines in resistance sensitive metallization layers, a maximum cross-sectional area may be obtained for the metal line with a high degree of process uniformity irrespective of a variation of the via density.

By providing a protection layer at the bevel region, the deposition of polymer materials during the patterning process of complex metallization structures may be reduced. Additionally or alternatively, a surface topography may be provided, for instance in the form of respective recesses, in order to enhance the degree of adhesion of any materials deposited in the bevel region during the manufacturing of complex metallization structures. Advantageously, the provision of the protection layer providing the reduced polymer deposition may be combined with the modified surface topography.
