Patent ID: 7491582

Claim:
A method for manufacturing a semiconductor device comprising: providing a connecting body including: a connecting electrode; and at least one semiconductor chip stacked on the connecting body, the semiconductor chip including: a substrate; and a trans-substrate conductive plug that penetrates the substrate, the trans-substrate conductive plug having: a first terminal that is provided on an active surface side of the substrate; and a second terminal that is provided on a back surface side that is opposite the active surface side, an outer shape of the first terminal being formed larger than an outer shape of the second terminal; providing a brazing material on the connecting electrode of the connecting body; stacking the semiconductor chip on the connecting body with the second terminal of the semiconductor chip being placed against the connecting electrode of the connecting body; and electrically connecting the connecting electrode and the second terminal via the brazing material by applying heat and pressure directly from a first terminal side to the first terminal.
