Patent ID: 7573135

Claim:
An electronic parts packaging structure comprising: a wiring substrate including a wiring pattern; an insulation film made of a single layer, formed on the wiring substrate; an electronic parts including a connection terminal and a passivation film having an opening portion for exposing the connection terminal on an element formation surface, the electronic parts being buried in the insulation film in a state where the connection terminal is directed upward and being mounted in a state where an upper surface side of the electronic parts is not buried in the insulating film, a lower portion of the insulating film whose thickness is thicker than a thickness of the wiring pattern of the wiring substrate exists between the electronic parts and the wiring substrate, thereby a back side of the electronic parts is electrically insulated with the wiring substrate by the lower portion of the insulating film, and an upper surface side of the electronic parts is not buried in the insulating film; a via hole formed in a predetermined portion of the insulation film on the wiring pattern; and an upper wiring pattern formed on the insulation film and the electronic parts, the upper wiring pattern being connected to the wiring pattern through the via hole and connected to the connection terminal through the opening portion, the upper wiring pattern directly contacting the passivation film of the electronic parts.
