Abstract

A method of forming a flip chip device comprises providing a semiconductor die having a core area and a periphery area. The periphery area includes an electrostatic discharge (ESD) structure. The semiconductor die including includes at least one power conductor. A substrate having a source of power is provided. A first connection circuit is located within the semiconductor die core area to couple power between the substrate and the semiconductor die power conductor. The ESD structure is electrically coupled to the first connection circuit. The first connection circuit is electrically coupled to the substrate via a conductive bump.
