Abstract:
1. A stacked electronic component, comprising: a substrate having electrode portions; a first electronic component having first electrode pads connected to the electrode portions via first bonding wires, and adhered on the substrate via a first adhesive layer; a second electronic component adhered on the first electronic component via a second adhesive layer, the second adhesive layer containing an insulating filler maintaining a solid state at an adhesive temperature, the second electronic component having a protruding portion protruding outside from an outer periphery of the first electronic component and having second electrode pads arranged at an upper surface of the protruding portion, the second electrode pads being connected to the electrode portions via second bonding wires; and a sealing resin formed on the substrate to seal the first and second electronic components, the first and second adhesive layers, and the first and second bonding wires, wherein the second adhesive layer is made of an epoxy resin, and the insulating filler is made of at least one selected from the group consisting of an urethane resin, a polyimide resin, and an acrylic resin, wherein the second adhesive layer is softened or melted at the adhesive temperature at which the second electronic component is adhered, and the second adhesive layer containing the insulating filler is filled between a lower surface of the protruding portion and the substrate, and wherein the insulating filler is a spacer having a size keeping a distance between the first and second electronic components.
