Abstract
A semiconductor device includes a substrate having a first surface, a second surface opposite to the first surface, conductive connections provided on the first surface, and columnar electrodes each extending from a corresponding one of the conductive connections toward the second surface, each of the columnar electrodes having a tapered shape; and a semiconductor chip having a third surface facing the first surface and a plurality of connection bumps provided on the third surface, each of the plurality of connection bumps electrically connected to a corresponding one of the plurality of conductive connections. A first one of the columnar electrodes, located in a first region of a chip region, has a first tapered shape. A second one of the columnar electrodes, located in a second region of the chip region, has a second tapered shape different from the first tapered shape.
