  • Patent number: 8785318
    Abstract: A technique which improves the reliability in coupling between a bump electrode of a semiconductor chip and wiring of a mounting substrate, more particularly a technique which guarantees the flatness of a bump electrode even when wiring lies in a top wiring layer under the bump electrode, thereby improving the reliability in coupling between the bump electrode and the wiring formed on a glass substrate. Wiring, comprised of a power line or signal line, and a dummy pattern are formed in a top wiring layer beneath a non-overlap region of a bump electrode. The dummy pattern is located to fill the space between wirings to reduce irregularities caused by the wirings and space in the top wiring layer. A surface protection film formed to cover the top wiring layer is flattened by CMP.

    Abstract: A planarization method of manufacturing a semiconductor component is provided. A dielectric layer is formed above a substrate and defines a trench therein. A barrier layer and a metal layer are formed in sequence in the trench. A first planarization process is applied to the metal layer by using a first reactant so that a portion of the metal layer is removed. An etching rate of the first reactant to the metal layer is greater than that of the first reactant to the barrier layer. A second planarization process is applied to the barrier layer and the metal layer by using a second reactant so that a portion of the barrier layer and the metal layer are removed to expose the dielectric layer. An etching rate of the second reactant to the barrier layer is greater than that of the second reactant to the metal layer.
