  • Patent number: 7084510
    Abstract: A semiconductor device has an active element structure formed on a semiconductor substrate. A first insulating film is provided above the semiconductor substrate. A first interconnect layer composed of copper is provided in a surface of the first insulating film. A second insulating film is provided on the first insulating film. A connection hole is formed in the second insulating film and has its bottom connected to the first insulating layer. A connection plug composed of a single crystal of copper is filled in the connection hole so that no other crystals of copper are provided in the connection hole. An interconnect trench is formed in a surface of the second insulating film and has its bottom connected to the connection hole. A second interconnect layer is provided in the interconnect trench.

  • Patent number: 7042088
    Abstract: The present invention includes a semiconductor package that forms the solder array joints on the die surface and corresponding BGA substrate and PCB respectively. The life times of array solder joints are increased through the use of two sets of array joints. The top array comprises a plurality of high melting solder joints and a plurality of low melting solder joints, while the bottom array comprises a plurality of high melting solder joints only. The reflow temperature of SMT assembly is between the aforementioned high melting point and low melting point of solder joints. In addition, each solder joint comprises a flat surface at its front edge.
