Abstract:
A semiconductor device includes a circuit substrate having a first metal layer on a first side, a second metal later on a second side, and an insulating layer between the first and second metal layers. A semiconductor chip is on the first side of the circuit substrate. A metal plate is on the second side. A solder layer is between the metal plate and the second metal layer. The second metal layer includes a protruding region which extends to a first thickness towards the metal plate, a first recessed region, and a second recessed region, each adjacent to the protruding region. The first recessed region extends to a second thickness that is less than the first thickness, and the second recessed region extends to a third thickness that is less than the first thickness.

Claim (Index 8):
The semiconductor device according to  claim 1 , wherein the semiconductor chip is disposed on the circuit substrate and the first protruding portion is sized and positioned such that:\n an angle between a first line segment virtually connecting a first edge of the semiconductor chip on a first end of the semiconductor chip and a boundary between the first protruding region and the first recessed region at a solder layer interface and an interface between the second metal layer and the insulating layer is 45 degrees or less, and an angle between a second line segment virtually connecting a second edge of the semiconductor chip on a second end of the semiconductor chip and a boundary between the first protruding region and the second recessed region at the solder layer interface and the interface between the second metal layer and the insulating layer is 45 degrees or less.
