  • Patent number: 7598605
    Abstract: A primary side circuit and a secondary side circuit are provided on first and second semiconductor substrates, respectively. A first capacitive insulator on the first substrate electrically insulates and isolates between the primary and secondary side circuits while permitting signal transmission between these circuits. A second capacitive insulator on the second semiconductor substrate electrically isolates the primary and secondary side circuit while permitting signal transmission therebetween. First and second frames are provided for input and output of signals to and from the primary and secondary side circuits. External electrodes of the first and second capacitive insulators are connected together by a third lead frame via a conductive adhesive body including more than one solder ball. The first and second substrates and the lead frames are sealed by a dielectric resin.

  • Patent number: 6853063
    Abstract: Wire bonding or printed wiring board leads or, alternatively, lead frames or equivalents thereof are used to electrically connect external electrodes of high withstand voltage capacitors formed on a plurality of semiconductor chips. A driver circuit for signal transmission or receiver circuit for signal receipt formed on the semiconductor chips are electrically connected with substrate-side electrodes of said high withstand voltage capacitors, causing the plurality of semiconductor chips to be received within either a single package or a single module. Using this arrangement, a semiconductor device is capable of achieving both dielectricity and size reduction.

  • Patent number: 5300798
    Abstract: When a semiconductor integrated circuit device having a wiring structure of three or more layers is hierarchically considered as a collection of a plurality of functional blocks, each functional block is internally connected by wirings in the first wiring layer, in which wirings have their main extended direction prescribed to be the X-direction, and wirings in the second wiring layer, in which wirings have their main extended direction prescribed to be the Y-direction, formed over the first wiring layer. Wirings in the third wiring layer, in which wirings have their main extended direction prescribed to be the same as the wirings in the second wiring layer, formed over the second wiring layer, together with wirings in the first and second wiring layer, are used as signal wirings between functional blocks, while the wirings in the third wiring layer are used as power supply wirings for providing power supply to functional blocks.

  • Patent number: 5132806
    Abstract: Disclosed is a novel semiconductor integrated circuit device for use in a color VTR (Video Tape Recorder). Concretely, the semiconductor integrated circuit device comprises a substantially rectangular semiconductor chip which has a principal surface, a luminance signal processing unit and a color signal processing unit which are disposed at the positions of the principal surface opposing to each other, and a semiconductor region which is provided in the interspace of the principal surface between the luminance signal and color signal processing units opposing to each other and which is supplied with a bias stable A.C.-wise. Further, the semiconductor region is located substantially at the central portion of the semiconductor chip and is extended so as to intersect with one set of opposing sides of the rectangular semiconductor chip.
