  • Publication number: 20230238323
    Abstract: Interconnect structures including signal lines, power lines and ground lines are configured for improvements in routing and scaling. Vertical stacking of the relatively wide power and ground lines allows for additional signal tracks in the same footprint of a standard cell or other electronic device. Alternatively, vertical stacking of the signal lines allows an increased number of signal tracks. Such interconnect structures are formed during back-end-of-line processing using subtractive or damascene interconnect integration techniques.
