Abstract:
1. A method of manufacturing a semiconductor device comprising: (a) forming a groove on a first surface of a semiconductor substrate, a plurality of integrated circuits and electrodes being formed on the first surface; (b) forming an insulating layer on an inner surface of the groove; (c) forming a first conductive layer on the insulating layer on the inner surface of the groove; (d) grinding a second surface of the semiconductor substrate opposite to the first surface until the groove is exposed to divide the semiconductor substrate into a plurality of semiconductor chips each of which has a first conductive layer exposed on a side surface of each of the semiconductor chips, a sheet being provided over the first surface and a filler material being provided between the first surface and the sheet, and the filler material being formed integrally over the first surface and in the groove; (e) stacking the semiconductor chips; and (f) electrically connecting the first conductive layer of one of the semiconductor chips with the first conductive layer of another one of the semiconductor chips.
