Abstract:
1. A method of manufacturing a semiconductor device, comprising the steps of: (a) preparing a semiconductor chip where a bump electrode is formed over a main surface and a thermosetting insulating film is formed over a back surface; (b) preparing a base board which serves as a core of a multilayered wiring board and in which a first internal wiring is formed; (c) applying a thermosetting resin to a chip mounting region of the base board; (d) after the step (c), coupling the bump electrode formed over the semiconductor chip with the first internal wiring by mounting the semiconductor chip, while heating the semiconductor chip, in the chip mounting region of the base board through the thermosetting resin; (e) after the step (d), applying a heat treatment; (f) after the step (e), forming a first interlayer insulator so as to cover a side surface of the semiconductor chip and to allow the insulating film formed over the back surface, which is on an upper surface side of the semiconductor chip, to be exposed; and (g) after the step (f), forming a second interlayer insulator covering from the first interlayer insulator to the semiconductor chip so that the conductive film may come in contact with the insulating film, the patterned conductive film being pasted to the upper part of the second interlayer insulator, and forming a second internal wiring comprising the conductive film so as to be directly in contact with the insulating film, wherein, by being heated in the steps (d) and (e), in a stage before the step (g), the insulating film is more cured than the insulating film in the step (a).
