    摘要: A system and method are provided to facilitate dual damascene interconnect integration with two imprint acts. The method provides for creation of a pair of translucent imprint molds containing the dual damascene pattern to be imprinted. The first imprint mold of the pair contains the via features of the dual damascene pattern and the second imprint mold of the pair contains the trench features. The via feature imprint mold is brought into contact with a first imaging layer deposited upon a first transfer layer which is deposited upon a dielectric layer of a substrate. The trench feature imprint mold is brought into contact with a second imaging layer deposited upon a second transfer layer which is deposited upon the first imaging layer of the substrate. When each imaging layer is exposed to a source of illumination, it cures with a structure matching the features of the corresponding imprint mold. A sequence of etches transfer and combine the via features from the first imaging layer with the trenches from the second imaging layer to create the dual damascene openings within the dielectric layer.

    摘要: Systems and methodologies are provided that account for surface variations of a wafer by adjusting grating features of an imprint lithography mask. Such adjustment employs piezoelectric elements as part of the mask, which can change dimensions (e.g., a height change) and/or move when subjected to an electric voltage. Accordingly, by regulating the amount of electric voltage applied to the piezoelectric elements a controlled expansion for such elements can be obtained, to accommodate for topography variations of the wafer surface.

    摘要: A system for monitoring and controlling the deposition of thin films employed in semiconductor fabrication is provided. The system includes one or more acoustic and/or ultrasonic wave sources, each source directing waves onto one or more thin films deposited on a wafer. Waves reflected from the thin film is collected by a monitoring system, which processes the collected waves. Waves passing through the thin film may similarly be collected by the monitoring system, which processes the collected waves. The collected waves are indicative of the presence of impurities and/or defects in the deposited thin film. The monitoring system analyzes and provides the collected wave data to a processor, which determines whether adjustments to thin film deposition parameters are needed. The system also includes a plurality of thin film deposition devices associated with depositing thin films on the wafer. The processor selectively controls thin film deposition parameters and devices to facilitate regulating deposition.

    摘要: A system for regulating an etch process is provided. The system includes one or more light sources, each light source directing light to one or more features and/or gratings on a wafer. Light reflected from the features and/or gratings is collected by a measuring system, which processes the collected light. The collected light is indicative of the dimensions achieved at respective portions of the wafer. The measuring system provides etching related data to a processor that determines the acceptability of the etching of the respective portions of the wafer. The system also includes one or more etching devices, each such device corresponding to a portion of the wafer and providing for the etching thereof. The processor selectively controls the etching devices to regulate etching of the portions of the wafer.
