The semiconductor package includes a semiconductor substrate, an insulating layer, a metal layer, an interposer substrate, a mounting substrate, a signal transmission solder ball, and a solder member. A pad is provided on one surface of the semiconductor substrate. A different surface of the semiconductor substrate is covered with the insulating layer. The metal layer covers the insulating layer. A wire to be connected to the pad is formed on the interposer substrate. The signal transmission solder ball is jointed to the wire and the mounting substrate, and transmits a predetermined electrical signal. The solder member is jointed to the metal layer and the mounting substrate.

  • Patent number: 7475843
    Abstract: A polygonal coil having a substantially square shape is manufactured by winding a conductive wire in the diameter direction of the core on the core in an overlapping manner by the use of a winding jig in which a first collar portion and a second collar portion are disposed at both ends of a core so as to be opposed to each other and four rod-shaped protrusions are disposed on a surface of the first collar portion opposed to the second collar portion so as to protrude in a radial shape centered on an end of the core,. As a result, it is possible to obtain a polygonal coil with high precision.
