Abstract:
1. A method of manufacturing a semiconductor device, comprising: (a) preparing a semiconductor substrate having an integrated circuit and an electrode electrically coupled to the integrated circuit on the first surface of the semiconductor substrate; (b) forming a through-hole in the electrode; (c) forming a concave portion in the semiconductor substrate, the concave portion communicates within the through-hole; (d) forming a conductive part within the concave portion, the conductive part formed within the through-hole; (e) thinning the semiconductor substrate by removing a part of a second surface of the semiconductor substrate so as to make the conductive part penetrate from the first surface to the second surface; (f) cutting the semiconductor substrate into pieces; and (g) inspecting an electric property of the semiconductor substrate through the conductive part after step (d) is finished.
