Patent ID: 7656041

Claim:
A semiconductor device comprising: a wiring substrate having a first surface and a second surface opposite to said first surface; a parts mount defined on said first surface for arraying and fixing a plurality of electronic parts; a plurality of connecting pads arranged in place outside said parts mount; and external electrode terminals on said first surface and/or said second surface; a plurality of electronic parts having a first surface and a second surface opposite to said first surface, said first surface having a plurality of electrodes and said second surface being fixed to said parts mount via a bonding material; a first underlying insulation layer having electrically insulating properties, provided between said connecting pads of said wiring substrate and said electrodes of said electronic parts and formed on said wiring substrate and on the surface of said electronic parts, wherein said connecting pads and said electrodes are electrically connected, a first metal layer formed overlaid on said first underlying insulation layer, one end of the first metal layer being connected to said connecting pads and the other end of the first metal layer being connected to said electrodes; a second underlying insulation layer having electrically insulating properties, provided between the respective electrodes, which are electrically connected, of adjacent electronic parts and formed on the surface of said electronic parts or on the surface of said electronic parts and between said electronic parts; a second metal layer formed overlaid on said second underlying insulation layer, one end of the second metal layer being connected to the electrodes of one of said adjacent electronic parts and the other end of the second metal layer being connected to the electrodes of the other one of said adjacent electronic parts; and a first surface insulation layer made of an insulating material for covering said first metal layer and a second surface insulation layer made of an insulating material for covering said second metal layer.
