Abstract:
A semiconductor device comprises a wiring substrate including a wiring pattern; a semiconductor chip installed on the wiring substrate, including a plurality of pads formed on a surface of the semiconductor chip, which opposes the wiring substrate; a first resin layer covering over a part of the wiring pattern within a region of overlapping the semiconductor chip; and a second resin layer installed between the semiconductor chip and the first resin layer. The pads are oppose to and coupled with a part of the wiring pattern exposed over the first resin layer; and the linear expansion coefficient of the wiring substrate is larger than that of the semiconductor chip, the elastic modulus of the wiring substrate is lower than that of the semiconductor chip and the linear expansion coefficient of the first resin layer is larger than that of the second resin layer. The elastic modulus of the first resin layer is lower than that of the second resin layer.
