Patent ID: 8334173

Claim:
A method for manufacturing a semiconductor apparatus, the apparatus including a semiconductor device including a first face and a second face opposing each other, and an electrode provided on the first face; a first external electrode opposing the first face of the semiconductor device, the first external electrode including a first major surface substantially parallel to the first face, a first side face substantially perpendicular to the first major surface, and a protrusion protruding in a direction perpendicular to the first major surface to connect to the electrode provided on the first face of the semiconductor device; a second external electrode opposing the second face of the semiconductor device, the second external electrode including a second major surface substantially parallel to the second face, a second side face substantially perpendicular to the second major surface, and an opposite face on a side opposite to the second major surface, the opposite face being substantially the same size as the second major surface; and an insulator covering the semiconductor device and the protrusion of the first external electrode, the first side face and the second side face being mounting faces, the semiconductor device being disposed between the first external electrode and the second external electrode, the method comprising: forming the protrusion made of a conductor on each of respective electrodes of the first face provided on a semiconductor wafer top face side of a semiconductor wafer; making trenches in the top face; filling an insulator into a gap between the protrusions and into the trenches to form a sealing member; grinding a bottom face of the semiconductor wafer opposing the top face until the sealing member is exposed to divide the semiconductor wafer into a plurality of semiconductor devices and to form a second face; forming a first lead made of a conductor on each of the protrusions, the first lead forming a portion of the first external electrode; forming a conductive material layer directly to form a second lead on the second face of the plurality of semiconductor devices, the second face formed by the grinding, the second lead forming the second external electrode; and cutting the sealing member between the plurality of semiconductor devices to separate the plurality of semiconductor devices from each other.
