Abstract:
1. A method of manufacturing a semiconductor device comprising: a semiconductor chip; a first conductor portion joined to a first main surface of the semiconductor chip; a second conductor portion joined to a second main surface opposite to the first main surface of the semiconductor chip; and a sealing resin portion for sealing the semiconductor chip and a part of the first conductor portion and a part of the second conductor portion, a surface of the first conductor portion being exposed from a first surface of the sealing resin portion, and a surface of the second conductor portion being exposed from a second surface opposite to the first surface of the sealing resin portion, the method comprising the steps of: (a) joining the first conductor portion to the first main surface of the semiconductor chip; (b) joining the second conductor portion to the second main surface of the semiconductor chip; (c) after the steps (a) and (b), forming the sealing resin portion for sealing the semiconductor chip and the first and second conductor portions in such a manner as to cover the surface of the first conductor portion; and (d) after the step (c), removing a part on the first surface side of the sealing resin portion, thereby allowing the surface of the first conductor portion to be exposed.
