An integrated circuit (IC) with electrostatic discharge (ESD) protection includes functional circuitry for performing processing functions required by the IC, and interface circuitry for providing an interface between the functional circuitry and components external to the IC. The IC is formed of a plurality of layers, including component level layers, power grid layers, and intervening layers between the power grid layers and the component level layers providing interconnections between the functional components. The functional circuitry further includes at least one ESD protection circuit constructed so as to reside solely within the component level layers in order to provide ESD protection for an associated one or more of the functional components. Such an approach enables the required ESD protection to be provided locally within the functional circuitry, whilst retaining flexibility with regard to the placement of, and routing between, the various functional components of the functional circuitry.
