Abstract
A semiconductor die includes resistor-capacitor (RC) clamping circuitry for electrostatic discharge (ESD) protection of the semiconductor die. The RC clamping circuitry includes building blocks distributed in the pad ring and in the core area of the semiconductor die. The building blocks include at least one capacitor block in the core area. The RC clamping circuitry also includes chip level conductive layer connections between each of the distributed building blocks.
