Patent ID: 8268673

Claim:
A method for manufacturing a stacked electronic component, comprising: adhering a first electronic component having first electrode pads on a substrate having electrode portions; connecting a first portion of the electrode portions and the first electrode pads via first bonding wires; adhering a second electronic component having second electrode pads on the first electronic component by using an adhesive layer structure including a first layer disposed at the first electronic component side and a second layer disposed at the second electronic component side; and connecting a second portion of the electrode portions and the second electrode pads via second bonding wires, wherein the first and second layers are made of a same material of thermosetting insulating resin, and the second layer has a modulus of elasticity larger than that of the first layer; wherein the first layer softens or melts at an adhesive temperature of the second electronic component, and has a viscosity within a range of 1 kPa·s or more and 100 kPa·s or less at the adhesive temperature, and the second layer maintains a layered shape for the adhesive temperature of the second electronic component, and has a viscosity of a range of 130 kPa·s or more at the adhesive temperature; and wherein ends of the first bonding wires connected to the second electrode pads are taken into a cured resin layer of the first layer, and a cured resin layer of the second layer is disposed between the first bonding wires and the second electronic component so as to prevent contact of the first bonding wires and the second electronic component.
