Abstract
A semiconductor device includes: a semiconductor layer; first and second vertical MOS transistors provided in the semiconductor layer; a metal layer in contact with and connected to an entire back face of the semiconductor layer; and a support bonded to the back face side of the metal layer via a conductive adhesive. In a plan view, the support is larger in area than the semiconductor layer and encompasses the semiconductor layer. A thickness of the support is greater than a thickness of the semiconductor layer. In a cross-sectional view of the semiconductor device including a center of the semiconductor layer and an outer periphery of the semiconductor layer in the plan view, a semiconductor chip resulting from excluding the support and the conductive adhesive from the semiconductor device is in a curved shape projecting in a direction away from the support.
