Patent ID: 7851265

Claim:
A method of manufacturing a semiconductor device including a semiconductor element having a plurality of electrodes, the method comprising: forming first wirings coupled to each of the plurality of electrodes, the first wirings each including a first land being located close to a center of the semiconductor element relative to the plurality of electrodes; forming a first resin layer on the first wirings; forming bore holes in the first resin layer over a part of the first land; forming second wirings on the first resin layer, each of the second wirings being connected to each of the first wirings via a respective bore hole, the second wirings each including a second land being located on an outer area of the semiconductor element relative to the bore hole; forming an external terminal on the second land; forming a second resin layer on the first resin layer and the second wirings, the second resin layer having a lower elasticity than the first resin layer; and forming a third resin layer on the second resin layer, the third resin layer having a lower elasticity than the second resin layer.
