摘要:
During the formation of a metallization layer of a semiconductor device, a cap layer is formed above a metal line and subsequently an implantation process is performed so as to modify the metal in the vicinity of the interface between the cap layer and the metal line. Consequently, an improved behavior in view of electromigration of the metal line may be obtained, thereby increasing device reliability.

A method is provided for preparing a sample for cross-section analysis by a transmission electron microscope. Semiconductor samples containing recessed portions or unfilled structures are filled with a filling material so as to produce a planar top surface onto which a metal layer can be deposited for thinning the sample to a thickness of less than 100 nm by an FIB technique.

By preparing fully-embedded interconnect structure samples for a cross-section analysis by means of electron microscopy or x-ray microscopy, degradation mechanisms may be efficiently monitored. Moreover, displaying some of the measurement results as a quick motion representation enables the detection of subtle changes of characteristics of an interconnect structure in a highly efficient manner.

By forming an appropriate material layer, such as a metal-containing material, on a appropriate substrate and patterning the material layer to obtain a cantilever portion and a tip portion, a specifically designed nano-probe may be provided. In some illustrative aspects, additionally, a three-dimensional template structure may be provided prior to the deposition of the probe material, thereby enabling the definition of sophisticated tip portions on the basis of lithography, wherein, alternatively or additionally, other material removal processes with high spatial resolution, such as FIB techniques, may be used for defining nano-probes, which may be used for electric interaction, highly resolved temperature measurements and the like. Thus, sophisticated measurement techniques may be established for advanced thermal scanning, strain measurement techniques and the like, in which a thermal and/or electrical interaction with the surface under consideration is required. These techniques may be advantageously used for failure localization and local analysis during the fabrication of advanced integrated circuits.

A semiconductor structure comprises a stress sensitive element. A property of the stress sensitive element is representative of a stress in the semiconductor structure. Additionally, the semiconductor structure may comprise an electrical element. The stress sensitive element and the electrical element comprise portions of a common layer structure. Analyzers may be adapted to determine a property of the stress sensitive element being representative of a stress in the semiconductor structure and a property of the electrical element. The property of the stress sensitive element may be determined and the manufacturing process may be modified based on the determined property of the stress sensitive element. The property of the electrical element may be related to the property of the stress sensitive element in order to investigate an influence of stress on the electrical element.

By digitizing the UFM signal without using a lock-in amplifier, substantially all of the information initially contained in the UFM output signal may be maintained and may then be used for further data processing. Consequently, any type of model or evaluation algorithm may be used without being restricted to a very narrow bandwidth, as is the case in lock-in based techniques. The digitizing is performed on a real-time basis, wherein a complete UFM curve is digitized and stored for each scan position. In this way, quantitative meaningful values for specific surface-related characteristics with a nanometer resolution may be obtained.

摘要:
An alloy forming dopant material is deposited prior to the formation of a copper line, for instance by incorporating the dopant material into the barrier layer, which is then driven into the vicinity of a weak interface by means of a heat treatment. As indicated by corresponding investigations, the dopant material is substantially transported to the weak interface through grain boundary regions rather than through the bulk copper material (copper grains), thereby enabling moderately high alloy concentrations in the vicinity of the interface while maintaining a relatively low overall concentration within the grains. The alloy at the interface reduces electromigration along the interface.
