  • Back end of line (BEOL) process corner sensing
    Patent number: 11823962
    Abstract: Aspects of the disclosure are directed to sensing integrated circuit (IC) Back End Of Line (BEOL) process corners. In one aspect, an apparatus for sensing IC BEOL process corners includes a ring oscillator including a plurality of ring oscillator stages configured to generate an output waveform with a frequency state; and a shield net circuit including a plurality of shield net stages corresponding to the plurality of ring oscillator stages, the shield net circuit having a toggle input. And, a method includes generating an output waveform with a frequency state using a ring oscillator that includes a plurality of ring oscillator stages; modifying a plurality of ring oscillator stage time delays through a coupling between a plurality of shield net stages and the plurality of ring oscillator stages; and selecting the frequency state using a toggle input of a shield net circuit which includes the plurality of shield net stages.
