Abstract
A system of protecting a proximity communication system against electrostatic discharge (ESD). The proximity communication system includes two chips, each having an array of electrical pads at its surface and covered by a thin dielectric layer such that capacitive coupling circuits are formed between the chips when they are joined together. In at least one of the chips, an additional protection pad is formed away from the array, and heavy protection circuitry is connected to it. Its surface is exposed through the dielectric surface over it such that, when an ESD aggressor approaches, the discharge occurs to the protection pad.
