Patent ID: 7888180

Claim:
A method for manufacturing semiconductor apparatus comprising: forming first projections made of conductive material on each electrode of one semiconductor device for each of a plurality of semiconductor devices, the electrode being formed on a front surface of a semiconductor wafer; forming a first groove between the semiconductor devices on the front surface of the semiconductor wafer; forming a first sealing portion by filling the first groove and a gap between the first projections with insulating material; polishing a back surface of the semiconductor wafer; forming second projections made of conductive material on the back surface of the semiconductor wafer, the second projections being connected to the semiconductor device; forming a second sealing portion by filling a gap between the second projections by insulating material; forming a first lead made of conductive material on one of the first projections; forming a second lead made of conductive material on one of the second projections; and separating the semiconductor devices by cutting the first and second sealing portions between the semiconductor devices.
