A structure for improving the electrostatic discharge robustness of an integrated circuit having an electrostatic discharge (ESD) device and a receiver network connected to a pad by interconnects. The interconnect between the pad and the ESD device has a high-k material placed adjacent to at least one surface of the interconnect and extending over the thermal diffusion distance of the interconnect. The high-k material improves the critical current density of the interconnect by increasing the heat capacity and thermal conductivity of the interconnect. The high-k material can be placed on the sides, top and / or bottom of the interconnect. In multiple wire interconnects, the high-k material is placed between the wires of the interconnect. A low-k material is placed beyond the high-k material to reduce the capacitance of the interconnect. The combination of low-k and high-k materials provides an interconnect structure with improved ESD robustness and low capacitance that is well suited for an ESD device. The interconnect to the receiver, which does not carry a high current, is surrounded by a low-k material for reduced capacitance and performance advantages.
