Abstract:
1. A semiconductor device, comprising: a semiconductor substrate having an electronic circuit provided on a main surface thereof; an electrode pad formed on the main surface of the semiconductor substrate; a wiring formed above the semiconductor substrate, the wiring electrically connecting with the electrode pad; a conductive post formed on the upper surface of the wiring, the conductive post electrically connecting with the wiring; an insulator formed on the lateral sides of the conductive post, the insulator comprising a thermosetting material; a sealing resin layer formed over the semiconductor substrate and the wiring, and on a surface of the insulator so that the insulator is sandwiched between the sealing resin layer and the conductive post; and an external electrode formed on the conductive post, the external electrode electrically connecting with the conductive post.
