    Abstract: The present invention involves a method for fabricating interconnecting lines and vias. According to the invention, copper is grown within the openings in a patterned coating. The patterned coating can be a resist coating or a dielectric coating. Either type of coating can be formed over a copper seed layer, whereby the seed layer is exposed within the pattern gaps. The copper seed layer can also be provided within the pattern gaps after patterning. Copper features (18) are grown within the pattern gaps by plating. Where the patterned coating is a resist, the resist is stripped leaving the copper features (18) in the inverse pattern image. The cooper features can be coated with a diffusion barrier layer and a dielectric (19). The dielectric (19) is polished to leave the dielectric filling the spaces between copper features (18). The invention provides copper lines and vias without the need for a dielectric or metal etching step. Another benefit of the invention is that lines widths can be increased by trimming the patterned coating prior to growing the copper features (18).

    Abstract: The present invention provides systems and methods that facilitate performing fabrication process. Critical parameters are valued collectively as a quality matrix, which weights respective parameters according to their importance to one or more design goals. The critical parameters are weighted by coefficients according to information such as, product design, simulation, test results, yield data, electrical data and the like. The invention then can develop a quality index which is a composite "score" of the current fabrication process. A control system can then do comparisons of the quality index with design specifications in order to determine if the current fabrication process is acceptable. If the process is unacceptable, test parameters can be modified for ongoing processes and the process can be re- worked and re-performed for completed processes. As such, respective layers of a device can be customized for different specifications and quality index depending on product designs and yields.

The system includes a wafer (610) that has a metal, polysilicon, and/or dielectric layer and/or substrate and electrical resistance member(s) and/or electrical resistance entities (110) located in and/or on the metal, polysilicon and/or dielectric layer and/or substrate. The system also includes a electrical resistance monitoring system (630) that can read the wafer (610) electrical resistance(s) from the electrical resistance member(s) and/or electrical resistance entities and that can determine wafer stress(es) based upon the electrical resistance(s) to characterize the chemical mechanical polishing process. Such characterization includes producing information concerning relationships between wafer electrical resistance(s) and polishing rate, polishing uniformity and introduction of defects during polishing. Such relationships are correlated with wafer electrical resistance(s) and polishing uniformity and introduction of defects during polishing. Such relationships ips are corrlated with wafer electrical resistance(s) (e.g., wafer stress(es) as related to parameters like polishing time, pressure, speed, slurry properties and wafer/metal layer properties.

The system (1000) includes one or more light sources (1020), each light source directing light to one or more features and/or gratings (1015) on a wafer (1010).

    Abstract: The present invention is directed to a method (58) for detecting asymmetry in the profile of a feature (82) formed on a wafer during the process of semiconductor fabrication. The method (58) encompasses directing a beam of light or radiation at a feature (66) and detecting a reflected beam associated therewith (68). Data associated with the reflected beam is correlated with data associated with known feature profile s(19) to ascertain profile characteristics associated with the feature of interest (192). Using the profile characteristics, an asymmetry of the feature is determined (192) which is then used to generate feedback or feedforward process control data (200) to compensate for or correct such asymmetry in subsequent processing.

    Abstract: The invention provides systems and processes that form the inverse (photographic negative) of a patterned first coating. The patterned first coating is usually provided by a resist. After the first coating is removed, where appropriate, to expose the patterned first coating. The patterned first coating is subsequently removed, leaving the second coating material in the form of a pattern that is the inverse pattern of the first coating pattern. The process may be repeated with a third coating material to reproduce the pattern of the first coating in a different material. Prior to applying the second coating, the patterned first coating may be trimmed by etching, thereby reducing the feature size and producing sublithographic features. In addition to providing sublithographic features, the invention gives a simple, efficient, and high fidelity method of obtaining inverse coating patterns.
