Abstract:
A method of manufacturing a semiconductor device comprising the steps of:forming cut grooves in a wafer which becomes a substrate, the wafer including a semiconductor layer which is disposed on the wafer via an insulating layer and at which a plurality of same semiconductor circuits are formed collectively, a surface oxide film which covers the semiconductor layer, and electrode pads for electrical contact with the substrate, the electrode pads being formed on the surface oxide film in correspondence with the respective semiconductor circuits, the cut grooves being formed in the wafer from the surface oxide film to the substrate, for separating the wafer into chips of the respective semiconductor circuits; and before separating the wafer into the chips, forming a conductive layer on groove surfaces of the cut grooves, the conductive layer extending from a substrate region via the groove surfaces of the cut grooves to the electrode pads.
