  • Patent number: 6728904
    Abstract: An electronic circuit package having a wiring substrate, at least two semiconductor chips and a bus line. All the semiconductor chips to be connected by means of the bus line are bare chip packaged on a wiring substrate, and the semiconductor chips and the wiring substrate are connected by wiring bonding between wire bonding pads formed on the semiconductor chips and the wiring substrate. The wiring substrate may be a multilayered substrate. Preferably, there is an insulating layer partially formed on the surface of the multilayer wiring substrate and a die bonding ground formed on the surface of the insulating layer, in order to use a portion of the multilayer wiring substrate under the die bonding ground as a wiring or a via hole region, and at least one of the semiconductor chips is formed on the die bonding ground.
