Abstract:
1. A method of manufacturing an electronic parts built-in substrate comprising the steps of: preparing a wiring substrate including a wiring pattern having connecting pads; forming a protection insulating film having an opening portion that exposes collectively a plurality of connecting pads of the wiring pattern on the wiring substrate by patterning a resist film; forming a plating layer on the wiring pattern containing the connecting pads in the opening portion of the protection insulating film; flip-chip connecting a bump of a first electronic part to the connecting pad; flip-chip connecting a bump of a second electronic part to the connecting pad arranged on an outside of a periphery of the first electronic part to package the second electronic part at a predetermined interval from an upper surface of the first electronic part; and filling a filling insulating body in a clearance between the first electronic part and the wiring substrate, and clearances between the second electronic part and the first electronic part, and the wiring substrate, to bury the first electronic part in the filling insulating body, the filling insulating body being formed to extend from a side surface of the second electronic part to a side surface of the opening portion of the protection insulating film.
