  • Patent number: 7923295
    Abstract: A semiconductor device is made by forming a photoresist layer over a metal carrier. A plurality of openings is formed in the photoresist layer extending to the metal carrier. A conductive material is selectively plated in the openings of the photoresist layer using the metal carrier as an electroplating current path to form wettable contact pads. A semiconductor die has bumps formed on its surface. The bumps are directly mounted to the wettable contact pads to align the die with respect to the wettable contact pads. An encapsulant is deposited over the die. The metal carrier is removed. An interconnect structure is formed over the encapsulant and electrically connected to the wettable contact pads. A plurality of conductive vias is formed through the encapsulant and extends to the contact pads. The conductive vias are aligned by the wettable contact pads with respect to the die to reduce interconnect pitch.

  • Patent number: 7919409
    Abstract: We have used the state-of-the-art computational chemistry techniques to identify adhesion promoting layer materials that provide good adhesion of copper seed layer to the adhesion promoting layer and the adhesion promoting layer to the barrier layer. We have identified factors responsible for providing good adhesion of copper layer on various metallic surfaces and circumstances under which agglomeration of copper film occur. Several promising adhesion promoting layer materials based on chromium alloys have been predicted to be able to significantly enhance the adhesion of copper films. Chromium containing complexes of a polydentate ?-ketoiminate have been identified as chromium containing precursors to make the alloys with chromium.

  • Patent number: 7919353
    Abstract: This invention is directed to offer a technology that makes it possible to form desired bump electrodes easily when the bump electrodes are to be formed at locations lowered by a step. There is formed an isolation layer 12 to isolate each of bump electrode forming regions 11. The isolation layer 12 is a resist layer, for example, and is formed by exposure and development processes, for example. Each of the bump electrode forming regions 11 is surrounded by the isolation layer 12 and a protection layer 10 that covers a side surface of a semiconductor substrate 2. Then, a printing mask 16 that has openings 15 at locations corresponding to the bump electrode forming regions 11 is placed above the semiconductor substrate 2. Next, solder 17 in paste form is applied to the printing mask 16. Then the solder 17 is applied to a metal layer 9 by moving a squeeze 18 at a constant speed. Bump electrodes 19 are obtained by heating, melting and re-crystallizing the solder 17 after removing the printing mask 16.
