  • Patent number: 8283247
    Abstract: In sophisticated semiconductor devices including copper-based metallization systems, a substantially aluminum-free bump structure in device regions and a substantially aluminum-free wire bond structure in test regions may be formed on the basis of a manufacturing process resulting in identical final dielectric layer stacks in these device areas. The number of process steps may be reduced by making a decision as to whether a substrate is to become a product substrate or test substrate for estimating the reliability of actual semiconductor devices. For example, nickel contact elements may be formed above copper-based contact areas wherein the nickel may provide a base for wire bonding or forming a bump material thereon.

  • Publication number: 20120235285
    Abstract: When forming complex metallization systems on the basis of copper, the very last metallization layer may receive contact regions on the basis of copper, the surface of which may be passivated on the basis of a dedicated protection layer, which may thus allow the patterning of the passivation layer stack prior to shipping the device to a remote manufacturing site. Hence, the protected contact surface may be efficiently re-exposed in the remote manufacturing site on the basis of an efficient non-masked wet chemical etch process.

  • Publication number: 20120088365
    Abstract: By moderately introducing defects into a highly conductive material, such as copper, the resistance versus temperature behavior may be significantly modified so that enhanced electromigration behavior and/or electrical performance may be obtained in metallization structures of advanced semiconductor devices. The defect-related portion of the resistance may be moderately increased so as to change the slope of the resistance versus temperature curve, thereby allowing the incorporation of impurity atoms for enhancing the electromigration endurance while not unduly increasing the overall resistance at the operating temperature or even reducing the corresponding resistance at the specified operating temperature. Thus, by appropriately designing the electrical resistance for a target operating temperature, both the electromigration behavior and the electrical performance may be enhanced.

  • Publication number: 20120049350
    Abstract: A semiconductor chip and a package substrate may be directly connected on the basis of form closure by providing appropriately shaped complementary contact structures in the semiconductor chip and the package substrate. Consequently, solder material may no longer be required and thus any elevated temperatures during the assembly process may be avoided, which may conventionally result in significant stress forces, thereby creating damage, in particular in very complex metallization systems.

  • Publication number: 20120051392
    Abstract: In a semiconductor device or test structure, appropriate heating elements, for instance in the form of resistive structures, are implemented so as to obtain superior area coverage, thereby enabling a precise evaluation of the thermal conditions within a complex semiconductor device. In particular, the device internal heating elements may allow the evaluation of hot spots and the response of a complex metallization system to specific temperature profiles, in particular at critical areas, such as edge regions in which mechanical stress forces are typically highest in contact regimes in which the package substrate and the metallization system are directly connected.

  • Patent number: 8114688
    Abstract: By forming a trench-like test opening above a respective test metal region during the etch process for forming via openings in a dielectric layer stack of sophisticated metallization structures of semiconductor devices, the difference in etch rate in the respective openings may be used for generating a corresponding variation of electrical characteristics of the test metal region. Consequently, by means of the electrical characteristics, respective variations of the etch process may be identified.

  • Patent number: 8053354
    Abstract: In complex metallization systems of sophisticated semiconductor devices, appropriate stress compensation mechanisms may be implemented in order to reduce undue substrate deformation during the overall manufacturing process. For example, additional dielectric material and/or functional layers of one or more metallization layers may be provided with appropriate internal stress levels so as to maintain substrate warpage at a non-critical level, thereby substantially reducing yield losses in the manufacturing process caused by non-reliable attachment of substrates to substrate holders in process and transport tools.
