Abstract
A semiconductor device includes a conductor, a semiconductor element, and a bonding layer. The conductor has obverse surfaces and reverse surfaces facing away from each other in a thickness direction. The semiconductor element has a body layer and electrodes projecting toward the obverse surfaces from a side of the body layer that opposes the obverse surfaces in the thickness direction. The bonding layer bonds the obverse surfaces and the electrodes. Each electrode has a base portion in contact with the body layer and a columnar portion projecting from the base portion and in contact with the bonding layer. The electrodes include a first electrode and a second electrode located closer to the periphery of the body layer than is the first electrode as viewed in the thickness direction. The second electrode is larger in area of the columnar portion than the first electrode, as viewed in the thickness direction.
