  • Patent number: 6388326
    Abstract: The present invention provides a bonding pad on a semiconductor chip such that peeling of bonding pads during interconnection in the packaging process is avoided. The bonding pad is used to electrically connect an integrated circuit in the semiconductor chip with an external circuit. The semiconductor chip comprises a first dielectric layer positioned in a predetermined area on the surface of the semiconductor chip, a second dielectric layer positioned on the surface of the semiconductor chip outside the predetermined area wherein the first dielectric layer is harder than the second dielectric layer, and a bonding pad positioned on the first dielectric layer for electrically connecting anintegrated circuit (IC) in the semiconductor chip with an external circuit.
