Patent ID: 8749041

Claim:
A semiconductor device, comprising: a substrate; a first semiconductor chip that is mounted face-down on the substrate; a second semiconductor chip that is mounted face-up on the first semiconductor chip, the second semiconductor chip being larger than the first semiconductor chip, the second semiconductor chip being provided with electro pads bonded to terminal electrodes on the substrate with bonding wires; a dummy chip that is interposed between the first semiconductor chip and the second semiconductor chip, the dummy chip being made from a homogenous material comprising silicon or an alloy containing an atomic percentage majority of silicon; an electronic component arranged below and within an outer boundary of the second semiconductor chip in plan view, the electronic component being mounted on a first surface of the substrate, the electronic component being arranged entirely within an area defined by the bonding wire, a lower surface of the second semiconductor chip, a side end face of the first semiconductor chip, a side end face of the dummy chip, and the first surface of the substrate, the electronic component being a resistor, capacitor or coil; and an adhesive layer disposed on the lower surface of the second semiconductor chip, a first part of the adhesive layer being disposed between the second semiconductor chip and the dummy chip, a second part of the adhesive layer extends beyond the dummy chip such that it is spaced apart from and does not contact the dummy chip, the second part of the adhesive layer being disposed between the second semiconductor chip and the electronic component, the second part of the adhesive layer facing a first surface of the electronic component, the first surface of the electronic component being opposite to a second surface of the electronic component, the second surface of the electronic component facing the first surface of the substrate.
