    摘要: A unified test structure which is applicable for all levels of a semiconductor device including a current path chain having a first half chain and a second half chain, wherein each half chain comprises lower metallization segments, upper metallization segments, an insulating layer between the lower metallization segments and the upper metallization segments, and connection segments. Each of the connection segments is electrically connected to a contact region of one of the lower metallization segments and to a contact region of one of the upper metallization segments to thereby electrically connect the respective lower metallization segment and the respective upper metallization segment, and the first half chain and the second half chain are of different configuration.

    摘要: By exposing a wet chemical cleaning solution, such as hydrofluoric acid, to a pressurized inert gas ambient prior to applying the solution to patterned dielectric materials of semiconductor devices, the incorporation of oxygen into the liquid during storage and application may be significantly reduced. For instance, by generating a substantially saturated state in the pressurized inert gas ambient, a substantially oversaturated state may be achieved during the application of the liquid in ambient air, thereby enhancing efficiency of the treatment, for instance, by reducing the amount of material removal of exposed copper surfaces after trench patterning, without requiring sophisticated modifications of process chambers.

    摘要: In a method of forming a semiconductor structure, an opening is formed in a layer of a dielectric material provided over an electrically conductive feature. An etching process is performed in order to form a recess in the electrically conductive feature. The bottom of the recess may have a rounded shape. The recess and the opening are filled with an electrically conductive material. Due to the provision of the recess, electromigration, stress migration and a local heating of the semiconductor structure, which may adversely affect the functionality of the semiconductor structure, can be reduced.
